Hello everyone,
I am new to working with D3 charts and would like to learn how to integrate them into Oracel Apex. So I started by integrating a D3 sunburst chart into Apex (https://bl.ocks.org/denjn5/e1cdbbe586ac31747b4a304f8f86efa5), which worked very well.
Now I wanted to integrate a Fishbone/Ishikawa chart (http://bl.ocks.org/bollwyvl/9239214), which unfortunately does not work.
Here is what I've done:
1. uploaded the d3.fishbone.js, data.json and style.css as a file into the application.
2. created a new page
3. created a region
4. inserted index.html from http://bl.ocks.org/bollwyvl/9239214 into region HTML code and adjusted file paths
When I execute the code, the following error is displayed (see below). What does this error mean? In Visual Studio Code, the code for the Fishbone/Ishikawa chart works fine, but in Apex it doesnt work.

Here you find the login data, if you want to have a look at my demo workspace
Oracle Apex Version: 22.2
Workspace: demo_
Name: demo
PW: demo1234
Application : 165269 – Fishbone
I would be very grateful for any advice!
Best Regards
Jegor
