setBrush

Enables rectangle brush selection on the chart. When a user drags to
select a region, the selected data points are available as a reactive
input in Shiny or exportable in static HTML.

Create interactive 'd3.js' visualizations from R with built-in
statistical transforms. Computes confidence intervals, regression fits,
LOESS smoothing, moving averages, error bars, and uncertainty
visualizations (quantile dot plots and fan charts) in R and renders them
as composable chart layers via 'htmlwidgets'. Supports 36 chart types
including boxplots, violin plots, Q-Q diagnostic plots, calendar heatmaps,
survival curves, and group comparisons with pairwise significance testing.
Also provides a machine-readable chart specification schema with validators
so that large language model agents can author and verify charts. Works in
'RStudio', 'Shiny', and 'R Markdown'.
