Description

https://open-bus-map-search.hasadna.org.il/velocity-heatmap?timestamp=1772363692959 the data takes a lot of time to be loaded, and there's no indication for the loading process. It makes users under the impression that this page is broken instead of waiting for the result to appear.

Contributor guide

Research direction
Look for the velocity heatmap component in the codebase, likely in the frontend directory. Identify where the data loading happens and add a loading indicator (e.g., spinner) that shows while data is fetching.
