Simple charts (bargraph, piechart, etc.)

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

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.)
