Description

Interesting project! The syntax of your library strongly reminds me of vega-lite, which itself is based on vega and the latter being itself based on d3.

I can see at least three advantages for your library, in particular the rendering part, if you built a renderer for vega:

  • vega is extensible, even on the rendering part, and thus you would benefit from an already available interactive grammar of graphics syntax - no burden of inventing a new one;
  • better focus on the rendering itself instead of users asking for implementing this and that type of chart;
  • your renderer would be accessible to js (via vega and vega-lite), R (via vega widget) and python (via altair) communities.

Contributor guide

Research direction
The issue proposes building a renderer for vega.js to generate xkcd style charts. The author references vega's extensibility API (vega.github.io/vega/docs/api/extensibility/) and renderer customization (vega.github.io/vega/docs/api/view/#view renderer). A contributor should examine chart.xkcd's existing source code (likely in src/) to understand the current rendering approach, then explore how to implement a custom vega renderer that applies xkcd styling to vega's scene graph. Reviewing the issue comments may provide additional guidance or constraints.
