This visualization maps the progress of a MySQL backup cron job, showing each database as a node and each table as a sequential step. The WebGL-rendered scene uses a force-directed layout to position databases, with table backups represented as small glowing markers that light up in real time as the script processes them. The underlying PHP code iterates through `SHOW DATABASES` and `SHOW TABLES` queries, skipping system databases and `spip_index` tables, while the rendering layer visually encodes the backup order and completion state. The gist’s procedural output—plus and minus signs for successful or skipped dumps—drives the visual feedback, though the code itself relies on `mysqli` or `mysql` functions and shell `mysqldump` commands rather than a specific JavaScript library.
