CAR-TER / Open Data Studio / 20 templates

Pick something
worth exploring.

Follow a river. Read the energy mix. Explore a public-domain collection. Twenty working templates turn public information into small, understandable instruments.

Available in the app under Templates → Featured. No local hub or API key to configure. Each template includes a walkthrough, source credit, and a visual storytelling idea.

The illustrations below use dated research snapshots, not live values or device screenshots. The native templates fetch refreshed data. Public APIs have different licenses and availability limits; every template includes its source terms.
