Analytics dashboards

Three interactive dashboards built with plain HTML, JavaScript and SVG from public datasets. Each one has KPI tiles, filters, drill-downs, a trend or cohort view, and a data table behind every chart.

These dashboards are open-tool implementations. Power BI and Tableau versions are not included in this repository; the step-by-step build guide and cleaned CSV exports for making them are in docs/build-in-bi-tools.md. Metric definitions are in docs/metrics-dictionary.md. Original work is licensed CC BY-NC-ND 4.0; the datasets keep their own CC BY 4.0 licenses (see THIRD_PARTY_NOTICES.md).
