What it does

Compose polished charts (timeseries, bar, line, area, pie, scatter, or anything else the data calls for) from tabular data using the chartkit primitives, producing PNG, SVG, or self-contained interactive HTML. Use when the user asks to chart, graph, plot, or visualize data and wants something better than raw matplotlib

Skill instructions

Graphing You write the plotting code. The kit provides the parts that should stay consistent across every chart: typography, color derivation from the background, the title and caption frame, and offline HTML packaging. Everything about the chart itself is your judgement applied to the data in front of you. The primitives Import chartkit by putting this skill's scripts/ directory on sys.path. Use its absolute path, not a relative path, since your working directory is the user's project. The examples below write it as /path/to/graphing/scripts; substitute the real path. Relevant primitives: - theme(bg, font): sets matplotlib rcParams and returns resolved colors. Foreground colors derive from background luminance, so a dark bg produces a correct dark chart. Fields: bg dark text muted grid spine accent secondary series fontcss. - palette(n, base): n colors. No base cycles the default series, a hex base builds a ramp from it, a list cycles the list. - finish(ax, title, subtitle, source): T
