Sunburst Disk Rings

A lightweight Linux alternative to HDGraph for radial concentric disk space
visualization. Independent open-source Linux tool, not affiliated with,
sponsored by, or endorsed by HDGraph authors.

CONCENTRIC MULTI-RING SUNBURST CHART
• Scans real local and mounted directory hierarchies with POSIX os.scandir
and renders a custom radial pie and concentric ring diagram.
• Hover any ring wedge for live folder summary, depth level, direct files
size, subtree total size, and direct children percentage shares.
• Click any folder arc to zoom the center root into that directory, click
the center root disc to zoom back up, or navigate via breadcrumb trail.

RING BREAKDOWN TABLE & GEOMETRY CONTROLS
• Explore a sortable directory breakdown table showing depth level, direct
size, total subtree size, share percentage, file count, and timestamps.
• Tune max ring depth (2 to 8 levels), minimum slice angle threshold, center
disc radius, color palette, and radial angle labels in real time.
• Inspect mounted filesystems via /proc/mounts and os.statvfs, and export
high-resolution PNG chart snapshots, SVG radial vectors, or CSV tables.
