Which Theme flags and Plot settings each mark honors. A blank cell means the mark ignores the flag today, or the call does not compile or raises; the column’s small print says which. Generated from each mark type’s supports_* constants (dataviz/marks.mojo) by pixi run docs, and checked against every mark’s rendered output by tests/test_feature_support.mojo, so the page and the code cannot disagree.

Notes

• Theme.tooltips, Plot.tooltips(): each datum gets an SVG <title>, shown as a hover tooltip. Tooltips.AUTO, the default, draws them only when a plot has at most Theme.auto_tooltip_limit (1,000) of them; Tooltips.ON on another mark raises.
• Theme.show_data_labels: each value is drawn as text; other marks ignore the flag.
• horizontal=True: the axes swap; other marks ignore the flag. GANTT, SPAN_CHART and EVENTPLOT are horizontal by construction and take no flag.
• annotate_line(), annotate_area(): a reference line or shaded band across a continuous y axis; on a typed chart the call does not compile for other marks, and raises at render time otherwise.
• annotate_vline(): a reference line across a continuous x axis; the call does not compile for other marks.
• annotate_band(), point, arrow, best_fit: overlays placed on continuous x and y axes; the call does not compile for other marks.
• scale_x_log(): a logarithmic x axis; the call does not compile for other marks.
• scale_y_log(): a logarithmic y axis; the call does not compile for other marks. AREA and HISTOGRAM force their y domain through zero, which has no logarithm.
• encode(color=, size=): a value or category per point drives its color or size; the call raises on other marks.
