d3-shape

Really fantastic work! Can't wait to play around with your library. I did a lot of work on this at a past job long ago and the state of JS tooling was so inadequate at the time we ended up building an in-house Scala visualization library to pre-render charts... More directly relevant, I haven't looked at the D3 internals for a decade, but I wonder if it might be tractable to use your library as a GPU rendering engine. I guess the big question for the future of your project is whether you want to focus on the performance side of certain primitives or expand the library to encompass all the various types of charts/customization that users might want. Probably that would just be a different project entirely/a nightmare, but if feasible even for a subset of D3 you would get infinitely customizable charts "for free." https://github.com/d3/d3-

An alternative if you want a bit more help with charting, without client side JS, is to use d3-shape (https://github.com/d3/d3-shape) to server-side render SVGs.

Thanks to d3, creating a new plotting library is not so hard https://github.com/d3/d3-shape You can regard this library as adding styles to d3 instead of chart.js

d3 has a lot of really useful libraries baked in. You can even use them independently and roll your own svg using its components as utilities. I find this super helpful when using d3 as a whole isn't really a good option (as part of a React/React-Native app for example). Such as: https://github.com/d3/d3-shape https://github.com/d3/d3-scale Doing it from scratch without the help of utilities like these would be much harder. A couple examples: var line = d3.line() .x(function(d) { return x(d.date); }) .y(function(d) { return y(d.value); }) .curve(d3.curveCatmullRom.alpha(0.5)); line(data); // gives you svg path and var color = d3.scaleLinear().domain([10, 100]).range(["brown", "steelblue"]); color(20); // "#9a3439" color(50); // "#7b5167"
