Hello again ,

I followed the advise given in the your reply for issue #499 . I checked the imports of all the needed packages you listed and they passed.
Then i created the following test :

1. stripped down the very same Python code of the example PyChartHTML's first tab (mpld3) : i commented out the two P4D-related lines (edge-browser) .
2. saved the new stripped code into a test.py Python modlue ,
3. then executed it from the Python command prompt. it executed successfully and displayed interactive chart in the browser (as seen in attached screenshot 1)
4. I then re-run the Delphi PyChartHTML demo, it failed again (as seen in attached screenshot 2), displaying the same error message as reported previously in issue P4D compatability with NumPy #499

the test setup (versions):

• Windows 11
• Delphi 12.1
• Python=3.12.3
• Numpy=2.2.4
• seaborn==0.13.2
• mpld3==0.5.10
• matplotlib==3.10.1
• pandas==2.2.3
• scipy==1.15.2

Whats now ?
