ShapeMap visualization extremely small

[kona134]

Hello,

I am building a custom map using the shape map visualization. I've managed to get the map working- however, the image when I put in the custom map is extremely small (pic included below):

Is there anyway to make this larger? I've tried playing around with various settings in mapshaper and QGIS (I am very new to this) to no avail. Any help is greatly appreciated!

Figured this out! If your visualization is extremely small, be sure and to check that there aren't any polygons that are outliers (there were several extra polygons far away from my main map- that was throwing everything off ). Delete those and you should be good to go!

This usually happens when the custom shape file has very small or offset coordinates, so the Shape Map visual zooms out too far. It’s not really controlled by a “size” setting in the visual — it depends on the geometry bounds of the TopoJSON/GeoJSON. (you could try with azure maps -native in Power BI) 

A few things to try:

• Re-export the map from QGIS/mapshaper after zooming to the layer extent and removing any empty or stray geometries

• Check there aren’t far-away features or tiny islands pushing the bounding box out

• Simplify and clean the geometry before export

• Make sure the projection is standard (WGS84 / EPSG:4326)

Once the bounding box is tighter, the map should render much larger in the Shape Map visual.

Best Regards!
