Getting Started with Flame

Now that you have installed Flame, you can start using it to analyze the performance of your code. Simply run your application with the perf tool and pipe the output to flamegraph to generate an SVG flame graph:

perf record -g your_application
perf script | flamegraph > output.svg

This will generate an output.svg file that you can open in your browser to view the flame graph.
