Leveraging the work done on framebox and fancy rough graphics, consider implementing some (basic) charts, such as

  • Bar graphs
  • Pie charts

Data could be read from CSV, using Penlight's pl.data.read()

EDIT:
Rationale: Potential niche addressed would be business-like reports, and also it's fun.

E.g. my initial "dirty" PoC from #25 :

Current version of the PoC now includes better bar graphs and initiates pie charts.

Caveat

  • PoC code is still ugly :)
  • This PoC will probably remain in this state for some time, as I am considering to move related developments to "ReSilient Types" outside the scope of the "Omikhleia" packages.
    • Next version will almost probably not be MIT-licensed
    • It will use (ported to Lua) a force-directed graph algorithm for proper label placement in pie charts (most likely one based on verlet-integration as this should likely be sufficient and I already coded one in JS and started porting it to Lua.)
