![]() Currently flame graph generation requires a d3-flame-graph template to be installed. Unfortunately this is hard to come by for things like Debian [1]. If the template isn't installed then ask if it should be downloaded from jsdelivr CDN. The downloaded HTML file is validated against an md5sum. If the download fails, generate a minimal flame graph with the javascript coming from links to jsdelivr CDN. v3. Adds a warning message and quits before download in live mode. v2. Change the warning to a prompt about downloading and add the --allow-download command line flag. Add an md5sum check for the downloaded HTML.
