Sorting Visualizer (sortviz)

This project generates step-by-step sorting visualizations as jgraph files, then converts them to PostScript and PDF.

Supported algorithms:

• bubble
• merge
• quick

Each step is rendered as a row of indexed squares with highlight colors:

• Yellow: compared indices
• Pink: value moving from this index
• Green: value moving to this index

Compilation and demo output

Build and generate demo outputs (PDF + JPG) with one command:

make

This compiles sortviz (if needed), runs several sorting scenarios, and writes showcase files to:

• tests/demo/*.pdf
• docs/images/*.jpg

Compile only

make build

Program usage

./sortviz <bubble|merge|quick> <values...>

Examples:

./sortviz bubble 5 1 4 2 8
./sortviz merge 38,27,43,3,9,82,10
./sortviz quick 10 7 8 9 1 5

Each run creates a timestamped folder under tests/bin/ containing one file per step in all formats:

• step_XXXX.jgr
• step_XXXX.ps
• step_XXXX.pdf
