maidr_plot_hook

Intercepts Base R plot output and converts to MAIDR iframe.
Uses iframe-based isolation to ensure each plot has its own MAIDR.js context.
Automatically falls back to image rendering for unsupported plot types or
non-HTML output formats (PDF, EPUB).
This replaces knitr's default plot hook when maidr_on() is called.

internal

Provides accessible, interactive visualizations through the 'MAIDR'
(Multimodal Access and Interactive Data Representation) system. Converts
'ggplot2' and Base R plots into accessible HTML/SVG formats with keyboard
navigation, screen reader support, and 'sonification' capabilities. Supports
bar charts (simple, grouped, stacked), histograms, line plots, scatter plots,
box plots, heat maps, density/smooth curves, faceted plots, multi-panel
layouts (including patchwork), and multi-layered plot combinations. Enables
data exploration for users with visual impairments through multiple sensory
modalities. For more details see the 'MAIDR' project
