#networkx

Got to wrap my head around graph theory as implemented in #NetworkX (a #Python package).

Obviously official docs are my starting point but if anyone can recommend good articles (including academic ones) that explain graph theory to beginners links would be very much appreciated.

Gone for good.
#NetworkX conference, Paris

A new release 3.2 of the incredible library NetworkX (the Network Analysis tool in Python)

Many improvements including Kemeny's constant on undirected and directed graphs.

Anybody have a favorite tutorial for how to draw pretty network (graph) diagrams using #NetworkX and #GraphViz

We're building calculation trees that represent the relationships between different fields in the FERC Form 1 (e.g. how hundreds of granular reported values aggregate up to a utility's balance sheet or income streams) based on XBRL metadata (which we've cleaned up significantly) but the default output leaves something to be desired.

The sx layer in the GeoPKG uses the centre-line track-model overlay on OpenStreetMap #OSM rail data based on minimum point to track distance

The ox uses only OSM data for track and meta-data tags

TIPLOC and STANOX locations are matched using the #NetworkRail OpenDataFeeds #CORPUS dataset

Code is developed in #python using #Geopandas #networkx #osmnx #Momepy #Shapely and #bash shell

1. Don't touch your code for 6 months.
2. Come back, do stuff, push... all tests fail -_-

Over these past 6 months:

- #shapely made their geometries immutable (that was a pain)
- #Networkx decided to move to #scipy sparse arrays, even though they are nowhere near finished and the move was almost guaranteed to break code
- #graph_tool moved a function to another module
- #matplotlib 3.7 made ArtlstList immutable
- #nest broke their ubuntu package

How's *your* day going?

Any #networkscience #complexsystems #netsci friends know off-hand which #networkX function reads this JSON format?

Summer time is open source time. Warm-up: Make sure that Python graph library #NetworkX can calculate minimum weight matchings of bipartite graphs without assuming that the underlying graphs are complete. [0]

This is useful whenever "something" has to be "assigned" to "someone" where each "someone" has preferences about what they're being assigned. [1] This turns out to be a common subproblem in combinatorics and constraint satisfaction.

For people interested in #networks and especially networks in #neuroscience, I just rolled out the latest version of my NNGT library (in Python)
https://frama.link/PAemKdSN

It provides a single interface to the three libraries #networkx, #igraph and #graph_tool, plus additional tools to build neuronal networks and simulate them with #NEST

Wrote a Clauset-Newman-Moore community detection package (fast modularity maximization) for #networkx. @aaronclauset@twitter.com
