Hi @cryptoref, thank you for posting in the community and @Humas1985 for sharing some posts to help with troubleshooting. 

There are a couple of issues that we consistently come up against with SVGs. Do you mind reading through and seeing if any of these could be the cause of what you are experiencing?

• Please try the SVG import in a Chrome Incognito browsing session. This often improves performance by clearing your cache and cookies and disabling your extensions.
• Our SVG import can only upload a file size of 150 KB or smaller. If you are attempting to upload a larger SVG, I would recommend downloading a smaller copy of that image and it should upload successfully.

Please let me know if you see any improvements after trying the steps above, or if you have any questions! 

OK so the problem is that the SVG is just too big, and this was only my test case, others will be much larger. 

But I’ve found that I was going the wrong way. What I want to do is create a CSV file and then make a heat map from that data. 

Thanks everyone for pointing me in the right direction. 

Thank you for the update, @cryptoref! I’m glad to hear the information was helpful. Please feel free to let us know if you have any questions - we’re happy to help!
