Based on many years using open source and commercial library:
1. The SVG option, when available, addresses the “resolution” problem. It create pdf (and may be HTML, did not try) that looks great at any resolution, including zoom.
2. Problem with both svg and png is that they are created for fixed aspect ratio. Works ok if the output is pdf or page like. Does not work well to when using mobile devices, or resized windows - the XY ratio is fixed at generation time. Also, svg does not
address well the need to keep fonts at readable size (e.g. 8-10 points) to attach labels to chart elements at fixed font size.
most open source server side) looks outdated, I would even say “boring”.
4. Users expect charts to be responsive, react to mouse overs, provide some animation, etc, server side charting usually not able to provide those.
Bottom line : built in charting is good for “static” reports - there are many good use cases for that, but they are many other use cases, especially for HTML reports/dashboard where “flashy” charts are expected.
