d3 is not defined

[LB26121]

While trying to use your package with react, the following error message appears permanently:

Uncaught ReferenceError: d3 is not defined

It doesn't matter how I import d3 or your package, the error always appears.
Which file do I need to import exactly? tidytree/dist/tidytree.min or tidytree/src/main.js ?
So far I import d3 in the same file -> import * as d3 from 'd3';

Packet versions:

• "react": "^16.14.0"
• "d3": "^7.8.4"
• "tidytree": "^0.5.9"
