# Analytics

The **Analytics** area (`/analytics`) is a public dashboard with
metrics and charts based on all tools and ratings.

## Metrics (KPI cards)

- **Number of tools** — how many tools are recorded in the catalog.
- **Number of ratings** — how many ratings were submitted in total.
- **Active categories** — how many categories exist.
- **Average rating** — global combined value.

## Charts

| Chart | Content |
| --- | --- |
| **Top 8 tools** | Bar chart of the tools with the highest combined score (0–5) |
| **Tools per category** | Radar chart of the number of tools per category |
| **Score distribution** | Two horizontal bar charts (usefulness & usability) per star |

The charts are interactive (tooltips on hover).
