maidr: Multimodal Access and Interactive Data Representation

Provides accessible, interactive visualizations through the 'MAIDR' (Multimodal Access and Interactive Data Representation) system. Converts 'ggplot2' and Base R plots, and experimentally 'lattice' charts, into accessible HTML/SVG formats with keyboard navigation, screen reader support, and 'sonification' capabilities. Supports bar charts (simple, grouped, stacked), pie charts, histograms, line plots, step plots, scatter plots, box plots, violin plots, candlestick (OHLC) charts, heat maps, density/smooth curves, faceted plots, multi-panel layouts (including patchwork), and multi-layered plot combinations. Also makes 'plotly', 'highcharter' and 'echarts4r' 'htmlwidgets' accessible by attaching the matching 'MAIDR' JavaScript adapter. Enables data exploration for users with visual impairments through multiple sensory modalities. For more details see the 'MAIDR' project <https://maidr.ai/>.
