Fit a map to a bounding box | UNL Map JS Docs

Use fitBounds to show a specific area of the map in view, regardless of the pixel size of the map.

Note

If you want to test this example, edit it in JSFiddle or CodePen and replace the "YOUR-OWN-API-KEY" and "YOUR-OWN-VPM-ID" placeholders with your actual api key and vpm id.
