UPDATED I have made a force directed graph using D3.js. Each node corresponds to a company, and each link corresponds how they are related to each other according to the link color. What I would like to achieve is to use the image URLs within "nodes" data and show a different image for each bubble. Currently I was able to set a fixed static/identical image for all of my bubbles. I tried to connect the pattern to my "nodes" data, but unsuccessfully which ended up in an infinite loop.
Simple HTML canvas for my svg and two buttons for the zoom in and zoom out by click.
<div style="overflow: hidden">
<div >
<div>
<button id="zoom_in"> </button>
<button id="zoom_out">-</button>
</div>
</div>
</div>
My datasets (links and nodes), note the image attribute on nodes. it refers to the image I wish to set as node background

CodePudding user response：
I've used your code to assemble a small example, which you can see below.
- Inside
svg > defs, create onepatternper node and use thatpattern(with the ID of the company) to fetch the logo of that company; - Reference the
patternfor the node using the information you already have.
Some pointers on your code:
- You already use ES6 logic, so you can also use
Array.prototype.mapand other functions. They're generally much more readable (and natively implemented!) thand3.map; - There is no need to keep so many arrays of values, generally having fewer sources of truth for your data will make the code simpler to maintain and update in the future;
- Use clear variable names! LS and LT are logical when you know the context, but when you revisit this code in 6 months you might not instantly know what you were talking about when you wrote it.
