Summary
Different point-and-click tools are available for working with graphs, from
acquiring and processing data, computing graph statistics, visualizing
graphs via various layouts and attributes, and providing interactions to
explore and filter the graph. Although each tool offers a breadth of features
across statistics, visualization, and interaction, each offers some unique
features as well, including the following:
• NodeXL provides social data acquisition with a couple of unique
layouts.
• Gephi provides rich interactive layouts and high-quality outputs.
• Cytoscape provides many visual attributes, flexible mapping,
annotations, and interactive output.
• yEd provides a variety of edge routing layouts and shape types.
Furthermore, you can use common file formats such as GraphML to process
a graph partially in one tool, and then you can transfer the graph to another
tool. However, some care is required because some features are not
supported in some products.
Sometimes, though, no combination of point-and-click tools is sufficient
for the task. Under these circumstances, you may need to look into
programming to achieve your objectives. Simple, lightweight programming
such as Python or JavaScript can be used to accomplish some specific tasks
(such as data preparation or customized interactive web visualizations).
Lightweight programming is the subject of Chapter 8.
