How to view a big svg file?

I have a big SVG file (~200MB): it's a graph with very precise data. However when gzipped into graph.svgz its size is around 3 MB, so you see it's very repetitive data. When I attempt to open it, Inkscape hangs and fills up the RAM, the only exit is reboot REISUB . I use Debian 10 with KDE desktop. Any idea to view the image ? It's OK to use another tool than inkscape, but I need to view the chart in detail, so generating a postage-stamp-sized PNG is not a good solution.
