Applying custom styles to lightweight-chart

ref: https://info.uniswap.org/#/
So I am trying to figure out how to make the createChart(...).addAreaSeries have a smooth line? And bring the labels from x-axis closer to the margin. I am look into Uniswap source code, however there is no hints.

lightweight-charts doesn't support smoothing lines yet (and probably won't).
As I can see from the picture and the page your referred there is no lightweight-charts, it is some other library (which uses SVG instead of canvas). Probably they use lightweight-charts somewhere else.

several questions regarding cytoscape.js

I've just started using cytoscape (with cytoscape-klay layout) to render some graphs and I'm unable to find answers to some of the questions I have:
Is there a way to left-align the graph? (graph seems to be centered horizontally, but in my use case, I need it to start from the left)
Edit: my graph is not pannable nor zoomable and panBy and shift doesn't seem to work
Is there a way to get the graph rendered without specifying the container dimensions? (right now, if I don't specify the dimensions, the canvas itself has a dimension of 0x0 and since I specify a width/height for every node, I think it should be possible)
Edit: I can't use an absolute positioned container since my view has some sticky parts. Also, I want the container dimension to be exactly what the graph needs as it is not pannable. I'm currently doing the following to accommodate both 1 and 2:
const dim = cy.$('*').boundingBox(); // get real size of graph
const container = document.getElementById('#cy');
container.setAttribute('style', `width: ${dim.w - 120}px; height: ${dim.h}px; transform: translateX(-175px)`);
Is there a way to define css in a css file or does it have to be in js?
Edit: I'm aware that I can use a js/json file - I'm wondering if I can also use a css file (I assume not, but I just want to make sure)
my nodes should be interactive (open / close) and since I work with Vue.js I prefer having my nodes as Vue components. while this seems impossible with cytoscape itself as it supports only a label for a node, I found nodeHtmlLabel package that gets me really close, it doesn't adhere to the styles that were set in js and reactivity seems to be a problem. Is there a better alternative?
Edit: I'm not asking about compound nodes. For a simple example of what I need, you can think of each node having a title and a description but only the title is visible and if you click on the node, it will open to show the description (node height would change)
can I customize the edges? (have an edge consist of a straight line connected to a bezier curved line, use my own control points, etc.) If not, how does these weights / distances work? do they work equally well for Top-Down and Left-Right graphs? (I'm trying to have something like this)
Edit: I'm aware of the current edge types, but I'm looking for something that is a merge between taxi and bezier. Since this is not currently supported, I wanted to know if there is any way to define a custom line myself
Background - I managed to get really close to the desired design with dagre-d3 but I have a problem with ranks and it seems that this package is unmaintained :(, hence I decided to look for an alternative

HTML Image map vs. multiple div elements

I am implementing an Angular component which has many little areas where user can click.
I see 2 ways how to do it:
use background image and define map areas where user can click, add click handler on the image.
use div for each clickable part and attach the click handler to parent element (so I don't have many click handlers on each div). Use the CSS to style each div so it looks like the image in 1.
The problem with 1. is that when the image changes I have to change the map coordinates too.
The advantage here is that it should work without problem in many browsers.
The advantage of the 2. is that I can style the component as I need (so it can be smaller, bigger, different font, etc.), but it can have performance impact when I need to show more than one such component.
Which way would you choose and why? Or are there any other possibilities?
Edit:
forgot to mention that the component should also work on mobile devices

I don't remember where but i just read a nice article about:
div(webkit-transform) vs svg vs canvas
To make it simple:
1-50 elements = divs & images
50-500 elements = svg
500 and more elements = canvas
this are here just to give you an idea ...then everything depends on every element and device.
Canvas would be the best solution for everything.
The problem on canvas is the click handler.You need to create a collision detection script.
(i used a canvas with a background image(worldmap),to show the dots in real time of the current users.).but it's not clickable... (there is a clickable legend under/over the map)
SVG is prbably the best solution in your case
like #mainguy said u can draw stuff and add eventHandlers (or one like on the parent element).and the performance is better than divs.
DIVS
Most of the time i use div sets with one eventhanlder. they are so easy to use and style.. but only squares or circles.. and if you start to style them you loose alot performance (box-shadow..).
If you don't style the divs you can use alot of them.Especially if you put the eventhandler on the parentNode.
that way you can handle 1000's of elements without problems.(but don't use position:absolute)
Image Map
Again ... if there are not too many elements this is prolly also a good solution.. the simplest ... (the simplest way to draw your simple shapes).As soon you have you static MAP values you can then transform your imagesize recalculation the map with the ratio.. so thats not a problem.
I would go for the image map if there are not to many elements.
else SVG.
Everything depends on how many elements you have.
is that when the image changes I have to change the map coordinates too
if you use divs you don't have to change coords?
** Mobile devices support more than ie browsers.

I would do this with a SVG library which are fast, easy to style and suporrted by most browsers.
D3.js
is available for Angular as directive. Have not worked with his one yet. But it seems to be very popular. Just look on their homepage for a WOW! effect.
Raphaël JS
Was used by me in many projects. It has the big advantage that it supports even old IEs (sic!).
Just make a search for Angular SVG and/or JS and you will find a lot of solutions.

Not knowing the exact requirements, my default choice would be 2.
There are drawbacks, such us inability to easily map non-rectangular areas. The advantages however are huge, including easy maintenance, possible responsiveness, more robust styling possibilities and more.
The sole amount of divs shouldn't cause any problems and I wouldn't worry about it.
There are cases in which I would look for different implementation, though.

Javascript Library to dynamically create graphs?

Here is my requirement:
I need to create a visualization of links between different representations of a person. The image below I think indicates that fairly clearly.
Additionally, those rectangles would also contain some data about that representation of a person (such as demographics and the place). I also need to be able to handle events when clicking on the boxes or the links between them, as a sort of management tool (so, for example, double clicking a link to delete it, or something along those lines). Just as importantly, since the number of people and links will varies, I need it to be displayed by spacing out the people in a roughly equidistant fashion like the image shows.
What would be a javascript library that could accomplish this? I have done some research and have yet not found something that can cleanly do this but I'm hardly an expert in those libraries.
Here are the ones I've looked at:
Arbor js: Can dynamically create the spacing and links of the graph but I'm responsible for rendering all the visuals and there's really no hooks for things like clicking the links.
jsPlumb: Easily create connections between elements and draws them nicely enough but doesn't seem to address any layout issues. Since I don't know how many people will be on the screen, I have to be able to space them out equidistant and that doesn't seem to be a concern of jsPlumb.
D3.js: This creates a good visualization with the spacing I need but I don't see how I can show the data inside each node or do things like like mouse events on the links or box.
I'm feeling a bit lost so I'm hoping someone could point me to something that could help me or maybe point me to an example from one of these libraries that shows me that what I want is possible.

I ended up using Arbor with Raphael as my rendering library and it's worked out very well.

Take a look at Dracula Graph Library. It's a simple library that seems to do both layout as well as rendering graphs (using Raphael under the hood). It's a bit underdeveloped however.

Hover effects on irregular polygons in CSS

I'm wondering how to go about marking up and coding hover effects for a map similar to this image.
When each district (or section) is moused over/touched/clicked I need to change the colour of it without affecting any other section. The boundaries on each section must be representative of the image and shouldn't be squares. The solution can't use canvas since the site I'm working on has to be usable in older browsers (I'm gutted, personally.)
Ideally I want to do this with CSS without using too much JavaScript or loads of images. Has anyone done this before?
Edit: I know people are suggesting the <area> tag, but AFAIK, it doesn't accept the :hover pseudo class.
Edit 2: I might use this: http://www.netzgesta.de/mapper/

Another self answer...
A few months ago I came across a library called Raphael JS - http://raphaeljs.com/. For those of you unfamiliar with it, it's an SVG DOM library first and foremost. If you know a thing or two about SVG, you'll know that IE doesn't support it, but it does support VML. Raphael caters for this as well. Awesome, right?
Anyway, I ended up saving the AI file for the map as an SVG file and importing the paths into a JSON block, basically doing the same thing as this code: http://raphaeljs.com/australia.html
The only issue I came across:
I wanted the map background to be transparent. Setting fill to transparent whilst allowing the section to accept mouseover worked in Firefox, but in IE, it failed. I instead opted for filling the path with white, then setting the opacity to 0.01. After that I duplicated the path and didn't fill it to create the border.

You can use HTML <area> Tag

If you use jQuery you can use the maphilight plugin. documented at http://davidlynch.org/projects/maphilight/docs/ and available from github at https://github.com/kemayo/maphilight

I see what the problem here is: making let's say a world map the usual way is quite a load. If I get it right, what you want is to have a territory map image and put hover effects making hover area match country borders exactly. SVG can be used for the map (the drawing part is already done) but the problem is how to generate HTML area map using SVG map coordinates. There's a solution (I've tried it, looks good at least with the demo provided) which translates SVG into Raphael (generates the coords) using PHP. But again you need raphael.js for that... well if you change your mind: https://github.com/atirip/svg2raphael. And if you're not familiar with Raphael it will take a time to get used to it, documentation is not so good -for me-.
Edit: I can confirm that translation from SVG->rapahel.js works but SVG files needs some tweaks. For what I see in the example SVG provided in svg2raphael the files were made with Adobe Illustrator. I've tried with SVG (plain) from Inkscape and it didn't work properly, but I could manage to fix the issues, for example:
svg2raphael won't translate Inkscape generated <path style="fill:#ff0000" ...></path> (will set fill="none"!!! so the result is invisible, but will translate correctly <path fill="#ff0000" ...></path> Seems like it will ignore everything inside style="".
svg2raphael misreads the alignments from Inkscape SVG, so you need to either move the illustration inside Inkscape or edit the SVG file with text editor and change the M value to M0,0.
svg2raphael can translate multiple svg elements, but looks at the main tag which Inkscape generates to align groups of illustrations, sometimes the whole illustration moves away from the render area and you see nothing. Hope this helps!
Edit 2: You can use Inkscape's style="" for creating CSS rules to apply to the SVG, that works great ang keeps style outside SVG/Raphael!
