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:
