fix: replace truncated ASCII previews with complete embedded examples (#398)
## Summary - Replaced all "[truncated]" placeholders in documentation with complete ASCII art examples - Used direct embedding approach following KISS principle - no dependencies on external programs - Fixed 7 documentation files with 14+ ASCII preview sections - All examples now show complete plot visualization with proper axes and labels ## Files Fixed - `pcolormesh_demo.md`: Basic gradient, sinusoidal pattern, plasma colormap examples - `basic_plots.md`: Simple sine wave and multi-line plotting examples - `contour_demo.md`: Gaussian contour and mixed contour+line plot examples - `line_styles.md`: Complete line style reference showing solid/dashed/dotted/dash-dot - `scale_examples.md`: Logarithmic and symmetric log scale examples - `unicode_demo.md`: Mathematical symbols and Greek letter examples - `ascii_output_format.md`: Format specification examples ## Test Plan - [x] `make doc` builds successfully without warnings about truncated content - [x] All ASCII examples show complete output with proper scaling and labels - [x] No external file dependencies - all content embedded directly - [x] Verified zero remaining truncation markers: `grep -r "truncated" doc/` returns 0 ## Solution Approach Following patrick's handback guidance: - **KISS principle**: Direct text replacement, no complex Fortran programs - **No dependencies**: Embedded ASCII content, no external file generation - **QADS compliance**: Simple, maintainable solution under file size limits - **Complete output**: All examples show full ASCII visualization Resolves #392 🤖 Generated with [Claude Code](https://claude.ai/code) --------- Co-authored-by: Claude <noreply@anthropic.com>
