Write flame graphs to SVG format and explore them interactively in Jupyter, Pluto, etc.

ProfileSVG

Purpose

ProfileSVG allows you to export profiling data as an SVG file. It can be used to display profiling results in Jupyter/IJulia notebooks, Pluto or any other SVG viewer.

An alternative visualization package is the GTK-based ProfileView. That package offers more interactive features. See the documentation for other visualization tools.

ProfileSVG is a package built on top of FlameGraphs. Among the Julia packages, ProfileView currently has the most comprehensive tutorial on how to interpret a flame graph.

Basic Usage in Jupyter

using ProfileSVG
@profview f(args...)

where f(args...) is the operation you want to profile.

The following screenshot illustrates Jupyter usage on a demonstration function profile_test:

You can hover over individual blocks in the flame graph to get more detailed information.
