Create interactive statistical charts, network graphs and choropleth maps. Charts are rendered with the 'ECharts' 'JavaScript' library, networks with 'Sigma.js' and maps with 'MapLibre GL JS'. A high-level interface of plotting functions builds a complete visualization from data in a single call, while a low-level interface gives full control over every option. Both are based on the same type-checked and validated 'S7' configuration objects. Configurations can be saved to and restored from 'JSON' files, and each chart type has a published 'JSON Schema' that other interfaces can implement. Visualizations display as 'htmlwidgets' that automatically adapt to light and dark themes, work in 'R Markdown', 'Quarto' and 'shiny', and can be exported to Scalable Vector Graphics (SVG) files using 'Node.js'.
