I built public data radars to see what is actually changing

Description and use

Palks Studio’s public radars aggregate data from multiple sources and display current indicators and recent trends, simplifying situational awareness without complex dashboards.

Problem

Data on the web is abundant but hard to interpret; users need a quick way to see current values and recent trends without complex dashboards.

Outcome

The radars offer a lightweight, account‑free interface that displays key indicators and their recent evolution, reducing the effort required to interpret changing data.

Workflow

• Collect data from diverse sources
• Validate and normalize the data
• Store in a database
• Aggregate for visualization
• Render SVG charts
• Log visits for analytics

Evidence

The radar is simply the last layer.

Source

The charts themselves are rendered directly as SVG rather than relying on a large charting library.

Source

Each radar records a minimal visit log.
