Configuration

Most Chartbuddy styling lives on chartData, not a separate options tree. Field map and layouts: chartData schema.

Title / subtitle / footnote	title, subtitle, footnote
Text boxes	multilines (free callouts)
Legend & palette	legend (docked / free placement, colors, …)
Axes, ticks, gridlines	axes.*.labels, axes.*.gridlines – see Axes
Labels (totals vs in-segment vs series names)	annotations.totals.visible, annotations.dataLabels, seriesLabels (see Labels)
Number formats	axes.*.labels.numberFormat, annotations.dataLabels.numberFormat, annotations.totals.numberFormat (see Number formats)
Type-specific look	bar, line, area, pie, …
