Here's a fictional example of what i'm trying to replace
http://ryanhollingsworth.com/test/map.html
Goal: input a series of state abbreviations and a hex value and have a dynamic map i can update quickly or use php to update on the fly.
I've been looking for a solution for a couple of weeks via google, figured i'd humble myself and ask. I don't want to reinvent the wheel and develop something that's already been done if i don't have to :) Thanks!
https://developers.google.com/chart/image/docs/gallery/new_map_charts should provide a quick and easy solution, although it is somewhat limited.
I used the Geochart API from google and I was able to create something very similar to your mockup image: http://cmoreira.net/interactive-world-maps-demo/usa-custom-election-map/
The API is very simple to use.

i need some advices. I have to add interactive, only Europe countries map in site. So i have looking the best js library to do this. The main purpose of the map is to open page with information about that country that i have been clicked.
You might want to check out AmCharts. Here's a simple demo of what seems to be what you need:
https://www.amcharts.com/demos/grouped-countries-map/
It's fairly easy to learn, much easier than D3 (at least in my opinion) which is of course another good library for the job.
I'm working on a javascript project to navigate pedestrians. I use openstreetmap to give me the needed map information. I'm using ajax-requests with overpass-api to get the streets and footways (separately).
What I want to find are intersections of streets and footways, that aren't marked as such. They could only overlap each other.
Is there an efficent Query to achieve this goal?
In principle, I do second scai's anwser: it's mostly better using already existing qa tools. But if you really want to go fancy with overpass, you can also get something like that with this somewhat complex (and probably not so über-efficient) query:
http://overpass-turbo.eu/s/1mk
Finding such errors via JavaScript would be very inefficient. What are you trying to achieve?
There are lots of quality assurance tools for OSM, some of them look for such missing intersections. One example is Keep Right. KeepRight offers a GPX export which you could use in your JavaScript application.
I am planning on making an analytics dashboard and would like to implement circular charts like the image attached to this question:
and I would like to do it using jQuery. Do you guys have any usefull links to resources or to other SO questions? Would be awesome!
Thanks!
You can also take a look at :
http://bernii.github.com/gauge.js/
http://www.justgage.com/
Both of them look really good and seems pretty easy to use.
The easiest way would probably be to create an SVG that mimics the appearance you want, and then use JavaScript/jQuery to modify the source of the SVG. The design you're requesting could probably be acheived by simply placing two arcs on top of one another.
Deriving from this excellent answer on calculating arcs, creating two overlapping ones could look something like this, which also demonstrates updating the arc dynamically.
lethargicpanda's suggestions are cool. Check out jQuery Knob too. It also allows user input.
I know there has been several discussions on JavaScript chart/graphics libraries, and there is many out there. What I need is one that can:
Zooming and panning
Data point manipulation (like when click on a data point, highlight other data points within the data series with the same certain parameter of the clicked one)
Dynamically change data point values (e.g.: dragging a data point dynamically updating the line shape)
Error bar support, horizontally and vertically
Select data points on the chart
Seems like Flot may have most of the features, if not all(not sure about 3, and 4), but would like to see if I don't miss out on there nice libraries.
Check out the awesome Visualization API on Google's AJAX APIs Playground
Take a look at http://raphaeljs.com/ library.
It has a plugin called gRaphaël which is charting plugin.
Look good but personally didn't use it.
Good luck and share you expirience if you try it.
The Dojo Charting Engine has a pretty astonishing featureset. Sadly dojo seems to suffer from a general lack of evangelism.
I dont know if there are good introductory tuts, maybe the best way is to learn from examples.
I'm searching for a Javascript library to create line charts like the ones of Google Analytics. When the mouse is over a point, a box shows you the data.
An example is at http://wikirank.com/en
No Flash or Air, only JS and client-side Canvas...
Better if Free...
Edit: If you want a free library, try Flot.
Emprise Charts is a commercial library that I've seen featured on news sites.
Another option is to use Google's visualization APIs.It's pretty easy to use, and they have a several options for displaying data. One thing to keep in mind is some of the visualizations require you to send your data to their server, though none of the canvas/svg ones have this requirement.
There's JS-Charts which looks pretty awesome.
Or, if you fancy rolling your own you can create your own charting component using this library...
As an alternative to Flot, if you are using Prototype.js as JS framework, you can use Flotr.
Dojo also has something similar, though the example shown doesn't have similar functionalities but can be implemented to behave like the one you want,
http://dojocampus.org/explorer/#Dojox_Charting_2D_Lines,%20Markers,%20No%20Axes,%20Purple%20Theme,%20Custom%20Min%20Max
Raphael.js is pretty good at making graphs with svg/vml, you have to write some custom code though, but you can make some really nice animation with it, next to that it's compatible with ie6+ (only not with android 2 browsers).
