create_fallback_iframe

Creates an iframe element with base64-encoded src containing a static image.
Used when plots contain unsupported layers and fall back to PNG rendering.
Unlike create_maidr_iframe, this does not include MAIDR.js dependencies.

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
<https://maidr.ai/>.
