Meet the same problem on version v5.4.1. You can see the demo here https://codepen.io/librabyte/pen/dyjNPXW .
Any suggestion would be appreciated, thanks for your efforts on this awesome project!

After reading docs from Echarts https://echarts.apache.org/handbook/en/basics/release-note/v5-upgrade-guide/#built-in-geojson-removed, here is the explain:
Built-in GeoJSON Removed
v5 removes the built-in geoJSON (previously in the echarts/map folder). These geoJSON files were always sourced from third parties. If users still need them, they can go get them from the old version, or find more appropriate data and register it with ECharts via the registerMap interface.

@MohammedAlSafwan, file /assets/worldmap.json does not exist anymore.
Here is how to use the geoJson world file with your code.
