dasImguiImplot tutorials

Step-by-step walkthroughs of the ImPlot surface. Each tutorial pairs an annotated source file under examples/tutorial/ with prose narrating the construction. Every example runs three ways unchanged — standalone (windowed), headless (--headless), and live (daslang-live) — because they are all built on the dasImgui harness. The interaction tutorials are additionally backed by a headless regression under tests/integration/ that drives or asserts on the same plot (e.g. test_query_and_hover moves the synthetic cursor onto the plot below and checks the reported position).

The tutorials build up in order: a first chart, then the v2 snapshot scope, the item families (areas, real-time, multiple axes, grids, statistics, categories), and finally the interactive surface (drag tools, colormaps, live query).

• Line plot
• Multi series
• Shaded and stairs
• Realtime scroll
• Multi axes
• Subplots
• Heatmap histogram
• Bar groups and pie
• Drag tools
• Colormaps and style
• Query and hover

Narrated, self-verifying screen recordings of each tutorial are a planned follow-up; each page will grow a Walkthrough section with its recording as they land.
