Using TopoJSON web link within Drilldown Choropleth visual

Hi All,

I have used TopoJSON link ("https://raw.githubusercontent.com/covid19india/covid19india-react/master/public/maps/india.json") directly in Drilldown Choropleth visual in one my report as shown in below image.

I do not have much idea on this, just wanted to understand, Is it safe to use link direclty into the report & it does not create any risk to the confidentiality of my data.

Would appreciate if somecan can help me how does it works & how my data safety is ensured while using topoJSON link.

Regards,

Dipali
