# Legend Explanation

The map legend displays the “Age of Data” and updates dynamically relative to the current date. It groups data into ranges (e.g., less than 1 year, between 1 and 2 years, more than 2 years) and shows a color ramp for each bucket.

Notes:

* The legend reflects the rendering style; exact colors may vary by theme.
* The legend updates to match your current map style and date filtering when applied.
* Use Jakartowns links to preview the location context when needed.
