Release Version v0.1.0-beta

Core Features

• Line plots & scatter plots
  Creating simple visualizations is easy using a friendly API similar to Python’s matplotlib.

• SVG output
  All figures render to an SVG file with no third-party dependencies.

• Automatic axis limits & “nice” tick generation
  Ensures plots look clean without requiring manual range specification.

• Text elements

  • Titles
  • X/Y axis labels
  • Basic layouting using browser-default font metrics

• Grid and legend support

  • Toggleable grid
  • Automatic legend generation when labels are provided

• Multiple subplots
  Use subplot(nrows, ncols, index) to construct multi-pane figure layouts.

• Header-only, C++17
  Drop the library into a project and compile—no linking or runtime dependencies.

Build & Tooling

• Requires CMake 3.15+
• Requires a C++17 compiler (MSVC, GCC, Clang)
• Ships with an example executable (catplot_example) demonstrating basic usage
• Builds cleanly on major platforms (validated via CI)

Limitations

These are expected for an initial release and will be improved:

• No PNG export yet (save_png() is present as a stub and throws)
• Text layout is approximate (no font metrics)
• Limited plot types (line/scatter only)
• Basic legend & grid styling
• Subplot layouting is simple and may need refinement
• Error handling is minimal
