Visualizing Tweet Graphs

Graphviz is a staple in the visualization community. This section introduces one possible approach for visualizing graphs of tweet data: exporting them to the DOT language, a simple text-based format that Graphviz consumes. Graphviz binaries for all platforms can be downloaded from its official website, and the installation is straightforward regardless of platform. Once Graphviz is installed, *nix users should be able to easy_install pygraphviz per the norm to satisfy the PyGraphviz dependency NetworkX requires to emit DOT. Windows users will most likely experience difficulties installing PyGraphviz,^[9] but this turns out to be of little consequence since it’s trivial to tailor a few lines of code to generate the DOT language output that we need in this section.
