CTAN update: gradbars
Version 1.1.0 expands gradbars with heat cells, box plots and distribution summaries, shared legends, and predefined color palettes. The table interface now supports native CSV binding, filtering, sorting, statistical summaries, and named shared scales. Compact numeric columns allow ordinary tabular cells to contain only numbers, reducing repeated markup. The tabularray adapter provides additional graphic column types. Other additions include bar and win-loss sparklines, domain report presets for correlation matrices, ablation studies and metrics, and public interfaces for third-party libraries and scalar rendering backends. The supplied renderer remains TikZ. Optional accessibility features include graphic descriptions and explicit table structure tagging. The illustrated English and Chinese manuals have been updated.

Gradbars – Compact data graphics for LaTeX tables and inline text
gradbars is a TikZ-based LaTeX package for drawing compact data graphics directly in table cells and inline text.
It provides ordinary and signed bars, stacked contributions, layered and dumbbell comparisons, floating intervals, lollipops, and sparklines. Features include shared scales, explicit missing-value handling, formatted labels, reference bands, target lines, error whiskers, conditional colors, CSV input, and reusable styles.
The package is tested with pdfLaTeX, XeLaTeX, and LuaLaTeX. English and Chinese PDF manuals include examples with rendered output and source code. The Chinese manual uses XeLaTeX; the English manual can be compiled with pdfLaTeX.
