State-Adjacency

README.md

If someone wants to travel through all the states he/she has to go through New-York since it is the connecting link between VT ,MA, CT, VI,RI ME,NH. ME is the only state that it is accesible accesible through only one state FL,SC,DC,WA are accesible only by two states, you can easily see then since they are on the boundary of the graph and connected only with two other states

This simple force-directed graph shows character co-occurence in Les Misérables. A physical simulation of charged particles and springs places related characters in closer proximity, while unrelated characters are farther apart. Layout algorithm inspired by Tim Dwyer and Thomas Jakobsen. Data based on character coappearence in Victor Hugo's Les Misérables, compiled by Donald Knuth.

Compare this display to a force layout with curved links, a force layout with fisheye distortion and a matrix diagram.
