Refactoring PyChart

on YouTube ↗42m

" summary

Refactors PyChart by making imports explicit, turning package module imports into direct class imports, and packaging class imports into a single pypchart module; it isolates file/format handling into a separate canvas/file-object layer, removes entangled globals, and makes output generation embeddable instead of relying on Python's exit hook. Tests use the shipped demo suite as regression checks (visual comparison done manually). Output formats include PDF, SVG, PostScript, PNG and planned HTML5 canvas output. Key changes: removed global state, extracted file backend classes.
