Google Location Visualiser (Use Chrome or Firefox)

The best way to get a complete location history is to go to Google Takeout and just select location history, after you extract the resulting zip the file you want to upload is LocationHistory.json
or to get a partial location history you can go to Google Location History and select a date range, click "Export to KML" and upload to this site.
Or click Here to download your complete history (Not 100%, Bit Dodge!).
