Importable test graph data

[thorwhalen]

A module with a few ready-made data to test on, as well as a few data generators in view of testing the visualization tools.

Criteria to keep in mind:

• number of nodes and links: Want to test small and large, sparse and dense
• structure: Want to test (visually) how specific structures render
• In general: How graph properties translate to visual characteristics

[thorwhalen]

@Stukova and @rokotyan : Are there any kinds of graphs that you can think of that had a notable effect on the visualization?
Such as: shed light on a bug, or looked weird, etc.

@thorwhalen Synthetic graphs usually work well for testing. Here's a massive 1000x1000 grid (1 million nodes, ~2 million edges): 1000x1000.csv.zip

Great. Thanks @rokotyan.

Yes, here I'm looking for things like
(1) small extremal examples that might reveal some problems
(2) properties of graphs that we can use to generate large graphs with those properties, so that we can test these things without a large storage overhead

The subject of a gallery of prepared "interesting" graph data and resources to find more raw sources is the subject of a different issue in my opinion, which I'll put here:

Resources of graph data users can browse and download
