I believe that would result in non accessible content, I believe screen readers cannot properly assist impaired users with SVG content.

As such I think it's not a good idea for a document that should have a large audience.

Is there any appropriate solution for complex interactive charts and graphs?

Good question. In general charts are not accessible because visually impaired users cannot use a mouse.

You would need an interacting charting library that works with a keyboard and that is readable by a screen reader.
