Summary
In this chapter, we worked on how to obtain and visualize a Facebook graph, detect communities, use color nodes, and apply some layouts with Gephi, such as Yifan Hu, Force Atlas, and Fruchterman-Reingold. Then, we introduced some statistical methods to get aggregate information, such as degree, centrality, distribution, and ratio. Finally, we developed our own visualization tool with D3.js, transforming the data from .gdf
into JSON.
In the next chapter, we will present a short introduction to the Twitter API to retrieve, visualize, and analyze tweets. Then, we will proceed to perform a sentiment analysis.
