Shape map extending from central point

[Anonymous]

Hi all

I have a custom shape map based on UK LSOA boundaries. While the data visualises fine in QGIS, it jumps out from a central point to present a warped map in PowerBI. There is also no visible gradient for the value I'm trying to visualise (LSOA deprivation data).

I am using the Equirectangular projection and have tried the others, but they don't work.

I downloaded the shape file from the government geoportal and then used MapShaper to convert to topojson. As context, I was able to visualise a similar shape map (also downloaded from the geoportal) using centroids and that worked fine. I have also tried using a clipped version of the LSOA polygon map, in case it was due to the map being too large, but I get a similar results. 

Any help would be much appreciated!

Thank you! Worked a treat.

The original map was using a OSGB36 projection, so I just converted it to WGS84 when exporting from QGIS. Simplifying it in MapShaper really sped things up too. Much appreciated!

export it from mapshaper using wgs84.-->  "-proj wgs84"

You might want to simplify the map first also, so that it doesn't take too long to render in powerbi.
