h2priograph is a tool that transforms the output of Chrome's HTTP2 net-internal tab into a graph, showing how H2 requests issued by Chrome depend on each other.

In addition to having go installed, running make should be all that's needed to build h2priograph.

• Navigate to a given HTTP/2 connection under chrome:https://net-internals/#http2
• Select all and copy, ctrl-A followed by ctrl-C
• Paste the contents to a file: On MacOSX: pbpaste > fastly
• Generate the dot file: h2priograph -file fastly > fastly.dot
• Generate an image (requires dot from graphviz) dot -Tpng fastly.dot > fastly.png
