ggplot-like geom coverage in ggWebGL

This overview links to the smaller coverage vignettes. The live applets are split across multiple pages to keep browser WebGL context use moderate and to make the article navigation readable.

Coverage Articles

Core ggplot-like WebGL layers: grammar-style workflow, renderer-ready specifications, core two-dimensional layers, rectangles, tiles, and bins.
Statistical and annotation WebGL layers: curves, contours, range summaries, filled regions, raster grids, annotation overlays, and fixed-scale facets.
Experimental 3D, mesh, and surface WebGL layers: 3D paths, structured-grid surfaces, unstructured meshes, and camera notes.

Status Labels

The split vignettes use conservative status labels:

Stable: core two-dimensional APIs with mature tests and renderer contracts.
Experimental: exported and tested APIs whose rendering contract or interaction details may still evolve.
Metadata-only: metadata serialization without a claim of full runtime parity.

These labels reflect API maturity, test coverage, and rendering-contract stability; they are not simply an export list.
