Webbrowser in PyCharm from codeline

Hi,

I am developing a plugin for PyCharm. I use Pyan3 to generate a static graph. Pyan3 gives me an HTML file as a result, which I want to display in PyCharm. I tried with the webbrowser.open(), but not worked.

Is it possible to open the html file inside pyCharm? (from code line)

Thank you for your help!
