tool-inventory

name	tool-inventory
description	Purpose-organised catalogue of validated data visualisation libraries, grouped by use case so a tool can be located quickly. Reference this at the start of any dataviz task to get a head start.

Data Visualisation Tool Inventory

This is a curated, purpose-first catalogue. It exists so that when a task arrives, the right tool can be located by jumping to the matching section rather than reasoning from scratch.

This is a guide, not a cage. Every entry here has been validated as a sensible default for its category. If none of them fit, reach for whatever works — but start here, because the categories below cover the overwhelming majority of real-world dataviz work.

How to use

1. Identify the task's primary purpose from the section headings below (e.g. "Graph / network", "Geospatial maps", "Story-driven animation").
2. Jump to that section.
3. Pick from the listed tools — each entry notes the sweet spot.
4. If nothing in the matching section fits, scan adjacent sections before going off-inventory.

Discovery beyond the inventory

The catalogue above is a head start, not an endpoint. If a task genuinely doesn't fit any category here, scan these topic feeds before committing to something arbitrary:

• https://github.com/topics/datavisualization
• https://github.com/topics/data-visualization
• https://github.com/topics/matlab

State explicitly when going off-inventory and say why nothing on the list fit.

Selection heuristic

1. Presentation medium → section (static → §1, web embed → §2/3/4, dashboard → §5/11, story → §6, graph → §7, map → §8, mobile → §9, exploration → §10).
2. Data shape → narrow within the section (time-series → uPlot/Lightweight Charts, tabular → ECharts/Plotly, network → §7, gridded/geo → §8).
3. Runtime → eliminate mismatches (Python-only, React-only, no-JS, etc.).
4. Interactivity level → pick the smallest tool that covers it.

Hand off to skills/choose-tool for the full decision protocol.
