D3.js Treemap Diagram - creating correspondence between data-value and cell area

Tell us what’s happening:

Hello everyone, I have tried to comb through other people’s solutions, but I still have not figured how I can change my treemap setup so that the tiles with larger values have larger areas. I would really appreciate any insight on this.

Your code so far

Here is the code concerned with setting up the treemap:

  const root = d3
    .sum(d => d["value"])
    .sort((a, b) => b["value"] - a["value"])
  const map = d3.treemap()
    .size([width, height])

Here is my full code: codepen

Hey guys, I found out that it’s a problem with the test itself. It expects the svg dimensions to be 960 by 570, otherwise the test is counted as a fail. The code itself is fine, and does not need any modifications.

Thank you! somebody should take this issue in attention I have spent several hours stuck there - is it so hard to put it on the list of stories?
