A data set of key tools used by 1000 highly successful software companies.
stacks.json contains a list of the companies and what techologies they use while graph.csv gives the set of edges used to create the following StackMap:
The graph is created by setting each tool to be one node and two nodes are joined by an edge if they are used simultaneously by a company - edge weight corresponds to how often tools are used together.
Graph visualisation is done in Gephi 0.92.
Node size corresponds to the amount of companies using a tool. If two tool are often used together then they will be closer together in the visualisation.
The data was gathered from public posts on Stackshare.io
