This patch adds generate-sampling-profiler-flame-graph, which generates flamegraph html file from JSC sampling profiler output.
For example,

    cat JSON/100/CPP/Speedometer3.0-TodoMVC-WebComponent.json | generate-sampling-profiler-flame-graph > result.html

can generate standalone flamegraph file.
