V8 Heap Statistics

Visualize object statistics that have been gathered using

• Use --trace-gc-object-stats for V8 and load the contents of stdout
• Chrome's tracing infrastructure collecting data for the category disabled-by-default-v8.gc_stats and directly load the results.html or trace.json.gzip file.

• You only get a data point on major GCs. You can enforce this by using the --gc-global V8 flag.
• For more frequent data points you can also the --gc-interval=$AFTER_N_ALLOCATIONS V8.
• The visualizer needs to run on a web server due to HTML imports requiring CORS.
