New: text from data, without TeX

This follows matplotlib's parse_math.

• plot.ParseMath(false) (FigOption) and Figure.SetParseMath(bool) set the figure's default, as rcParams["text.parse_math"] does.
• plot.PlainText() and plot.MathText() on one call act as parse_math=False and parse_math=True on that text.
• The calls that take them:
  • SetTitle(s, opts...), SetXLabel(s, opts...), SetYLabel(s, opts...);
  • the new SetXTickLabels(locs, labels, opts...) and SetYTickLabels(locs, labels, opts...), for category ticks;
  • Legend (every entry), Text, Annotate and Pie.
• A plain string is drawn character for character as outlines. It never reaches the TeX typesetter.
• The formatters' own tick labels stay math.

SetTitle, SetXLabel and SetYLabel gained variadic options. Calls compile unchanged, but method values change type.

Tests use $\input{/etc/passwd}$, <script> and 100$. A spy renderer checks that each string goes through plain layout. A control checks that the default still sends them to TeX. The SVG stays CSP-safe.

v0.2.0

go-plot/plot v0.2.0

New

• Axes.Pie and Axes.Donut: matplotlib's ax.pie.
  • Options: Labels, AutoPct/AutoPctFunc, PctDistance, LabelDistance, StartAngle, CounterClock, Explode, Radius, Center, WedgeWidth, RotateLabels, Normalize, TextColor, and the existing Colors, EdgeColor, Alpha, FontSize.
  • Each labelled wedge gets a legend entry.
  • Negative, NaN, infinite or all-zero sizes return ErrPieNegative, ErrPieNonFinite or ErrPieZero, in matplotlib's order.
  • Two go-plot additions: PlainText() keeps labels out of TeX, so $ is a dollar; SpreadLabels() moves the labels of thin wedges apart and draws leader lines.
• text.PlainRenderer (LayoutPlain).
• colors.Tableau10, the palette of go-widgets/toolkit's PieChart.

Changed: SVG output is safe to inline under a strict CSP

• Paint is written as presentation attributes (fill="…"), no longer as style="…".
• Clip ids are derived from their rectangle (c<hash>), not counted (c1, c2…). Two figures inlined in one page no longer clip each other.
• There is no script, no event attribute and no external reference. Text is glyph outlines.

Fixed

• cost \$5 drew its backslash.

Judges

Against matplotlib 3.11.2 (tools/gen_pie.py):

• wedge paths match vertex for vertex on 10 cases;
• every label's text, position and alignment match;
• the Axes box and the refusals match;
• 99.1–99.9% of the pixels agree with matplotlib's PNG, and a negative control is included.

Also:

• golden SVGs;
• FuzzPie;
• 100% coverage on 3 OSes and 6 architectures.

Not measured against matplotlib's speed: the load was above the gate. tools/compare/perf.py has the pie cases.
