How to install and use topojson in Power BI custom visual

[Madhumitha]

Hi,

I am developing a custom visual which is related to Map.

I am using D3 library for this. To draw a map, D3 is using topojson. 

I don't know where should I refer the topojson library in the custom visual.

I am referring the below link to develope the custom visual.

Kindly help me. 

Thanks in advance.

Hello,

Thank you for your reply.

Can I add any JSON file in the external folder which I want to use in my Javascript code.

@Madhumitha,

Just use JS instead for the time being.
