From: Spheres of legislation: polarization and most influential nodes in behavioral context
Histograms of edge weights. Best viewed in color, each plot shows frequency polygons, a form of histogram, of edge weights for the four spheres. Clockwise from top left: Democrat-to-Democrat, Republican-to-Republican, Republican-to-Democrat, and Democrat-to-Republican edges. The data are parsed into bins \((x_1, x_2], (x_2, x_3],..., (x_{n-1}, x_n]\). We then plot the number of data samples that appear in the bin \((x_{i-1}, x_i]\) against \(x_i\). The plots show how the influence weights in Sphere 1 (Security & Armed Forces)— shown in black dots—are different from the rest of the spheres
