The graphs were made by HUT research student
Mikko Kivelä
and University of Tampere grad student Bemmu Sepponen. A
simple PHP script was used to
create
Himmeli vertex and edge data (
vertices.txt,
edges.txt) from CrunchBase
API output. This resulted in the
messy graph, which was used
as a starting point to extract company and people connections with unipartite projection and then simplifying
these resulting graphs by creating a maximum spanning tree.
The graph image files are quite large. If you post them on a high-traffic site, please make
local copies so that our server doesn't die. Feel free to use them as you like!
Bonus: Google Number
See how many people are needed in between to connect a company to Google:
