@kjk The "interactive e book" is supposed to be used as unpacked SVG images the Author states "right-click on the image in the browser and select Open Image in New Tab" thus does not expect it to be used in an ePub document reader.

From https://github.com/labilezhu/istio-insider-en/blob/main/README.md

Interactive Books It can be said that most of my writing time is not spent writing, but drawing. Therefore, using a computer to read the pictures is the correct way to open this book. Mobile phones are just a conspiracy to drain traffic. Most of the diagrams here are more complex, not PPT big pie charts. Therefore, it is basically not suitable for printing out paper books. But I'll let the graph interact with the reader:

Original drawings, mostly SVG images made with Draw.io: *.drawio.svg. For complex diagrams, it is recommended to open with draw.io:

Some images provide a Open with draw.io link, which can be viewed in a more interactive way in the browser: Where there is (underlined text), links to related documentation and lines of code. Put the mouse on it and a hover window will pop up, prompting more information. Such as configuration file content. If you don't like draw.io then just look at SVG:

The correct posture to browse SVG images is to right-click on the image in the browser and select Open Image in New Tab. Large SVG image, middle mouse button pressed, free scroll/drag. SVG images can click the link to directly jump to the corresponding source page (or related documents), sometimes accurate to the source line.
