About the data
Every tool here follows the same pattern: an offline Python pipeline turns a public government (or utility) dataset into compact JSON, and a single self-contained HTML page renders it in your browser — no server, no account, no tracking beyond standard page analytics. Values are modelled or reported figures from the original source, not independently measured; each tool states its own caveats on-page.
Built by Ottawa Visuals, source on GitHub. Website, data pipelines and Python scripts were developed using Claude AI.
