I'am trying to create circle-packing chart like that
https://bl.ocks.org/mbostock/4063530
But I also want to create some relation between data, to show how data binds to each other, so I need to add some code to change example above to make it like on this image: Circle chart with relational links
So the question is: is it possible to add relational between children in array to reach desired behavior and change Circle-chart layout to Linked Circle chart layout?
P.S. I'm new in d3.js so I don't have deep knowledge in this field, so It would be great if you provide me some examples how to reach that
I've solved my problem my problem by myself, The solution is that to draw arrows by hands without d3 layout tools, I hope it could be useful for someone:

I am trying to create small multiples with d3 in react.
As reference i use this
https://observablehq.com/#nyuvis/small-multiples-with-different-axes
It seems to work fine, however it uses the area constructor but i actually want to draw bar charts as small multiples, and rectangles do unfortunately not have a constructor in d3 and i'm not sure how to adapt the code to work without using a constructor.
Therefore i also tried the example from the answer here
What is the best way to create small multiples in d3.js v6?
It works somehow, but in react all the bar charts are drawn on top of each other.
You can find my example here:

Thanks for your help!
I need to be able to draw links between the circles in a circle pack layout, like {source: i, target: j}. I've seen some questions about how to combine this layout with the force layout that made me think It could be a way to achieve this but I haven't had any luck on that path, also what I need is something completely static. Thank you in advance for any suggestions.
I finally could draw lines between nodes by appending them to the svg and calculating each line position based on the radius of the nodes that each line were to connect, but the problem was that the pack layout that I'm using is zoomable, so when I tried to zoom by clicking the lines neither translate nor re-sized (of course, since there was no code performing such things), so I tried to implement a translation function for the lines so they would move along with the zoom, then I saw that it would take some serious geometry to achieve this, so since I'm a lazy programmer and not at all experienced with d3 I tried to come with something more simple... at last I decided to represent the links between the nodes with a different approach (without lines), I used the "mouseover" event so when the pointer is over a node it will highlight (changed circle stroke attribute color and width) the nodes connected to it. This way I achieved my goal and the view looks a lot cleaner without all the lines crossing over it (they were a lot). I know that some may think that this does not answer the original question, and I'm sure that this can be achieved by someone with more experience (and time and patience) using lines and implementing the right calculation, but in my case this solution solves my problem and maybe it could be of help to others.
I really appreciate your help on this - I'm fairly new to D3.
I am working on a sort of nested D3 viz. When one element in the first D3 viz is moused over, I want a second D3 viz (say bar chart distribution of the first's elements) to appear. Is this possible? Could you give me a high level overview of how to implement?
To further illustrate: Let's say first viz is scatter plot of GDP vs. population of various countries. When a particular country on the scatter plot is moused over, I want a bar chart to appear in the tooltip that shows the top 5 industries in that country.
Any help on how to approach this would be much appreciate. Thank you again!
I suggest you to take a look into Bootstrap's "popover". I like it because is very easy to use. Inside that popover you can insert SVG element and draw your second visualization.
To keep things clean and reusable, I suggest you to read this article and write your second chart in reusable manner.
I' have an already made a Stacked/Group multi bar chart with NVD3 which is working great. I need to add a grey background to some of the places of the graphic to inform something to the user.
Does anybody know how to do this?
Thanks!
If I understand correctly you don't want a background for the whole chart. In this case you can always use d3's own insert method selection.insert(name, before) (see the documentation at https://github.com/mbostock/d3/wiki/Selections#wiki-insert ) to display an svg object at a certain in front / behind certain elements...(I guess it would be behind all the groups from you animation basically).
I have some code which generates an array; at each index there is an array with an x and y coordinate. I wanted to plot the points as a graph using d3.js, but am not sure how to go about that.
I have looked at the site and the examples but have found nothing that would help me with this task. This link here is an example of the type of graph I am trying to create, except I want to be able to create multiple graphs on one grid.
I basically need some guidance on how to get started, because I am completely lost. Any help would be appreciated.
This might better be a comment but I don't have comment access. First of all what is the name of the type of graph you link to in your question? It's not your basic pie or bar graph.
If you want multiple sets of data on one graph, what type of graph do you want? I can't visualize what you are trying to do so I don't know how best to help. Here is a good list of tutorials that link out to examples of how to use D3.
