SVG Reader not showing visualization

[P_S]

Hello community,

I would like to try using SVG Reader so I download from Github (https://github.com/brianwmunz/svgReader-QlikSense). After I download it, I place this one in C:\Users\{User}\Documents\Qlik\Sense\Extensions\SVG-Reader. It shows SVG reader extension in Qlik Sense Desktop and allow me to use the extension. But after I select the extension and select dimension and measure, the visualization go blank instead of showing country map (as in the image).

 How do I make this work? Any suggestions are welcome.
