About
DotChart is a Mac app for previewing DOT and Graphviz graphs. Use it alongside your favorite text editor, and the graph updates every time you save the file.
DotChart also lets you export your graph as a PNG with customizable margins, and you can export PNG from the Terminal using the command line. It fits right into macOS, with Quick Look support so you can preview your .gv files directly from the Finder.
The app includes syntax highlighting for DOT source, along with an easy way to take and share screenshots.
