Hi vikassan,
From v4 and upwards, D3 uses ES6 modules and requires a different syntax to import.
Support for ES6 modules in Power BI custom visuals was added in powerbi-visuals-tools version 3.1.0 , so firstly you need to ensure that you're using this or a higher version. If not, you will need to upgrade your project (and possibly code) to match the changes.
Provided you have the corresponding @types/d3 installed in your project for the version of D3 you're using, one of the following will work:
Entire package:
import * as d3 from 'd3';
d3.select(...Importing desired method only:
import { select } from 'd3';
select(...Regards,
