Describe the bug
I have added several bar graphs to my Angular 8.2.12 application, and they work beautifully. I recently added a heat map, and I am seeing the following error:

I have the same problem. As a workaround I use the angular-cli option --optimization=false.

I solved my problem. Updated version of @angular-devkit/build-angular from 0.801.0 to 0.803.17.

Having the same issue with latest angular packages. None of the solutions above worked.

Project works fine in npm start / jit mode, but not int AOT.

I think the issue is related to d3 packages. I solve this kind of problem with this solution.

The d3 packages have been updated in v 13.0.0. Closing this as fixed. Please open a new issue if you still see a problem.

Same as the issue: d3/d3-color#68
