I happened to visit https://www.oecdbetterlifeindex.org/ and I quite like the flower chart here. I want to try it for my own website but alas it’s too difficult for a non-font-end expert like me. Even though I tried to write it down roughly, it still seems like something of a disaster. Has anyone ever had an idea or done something similar? Please give me further instructions. Note: I am trying to code those charts in Javascript and some libraries I have tried like chartjs D3js, cavas, etc…
