Storing a graph in mongodb
Specialized Distributed Graph Databases I know this is sounds a little far afield from the OPs question about Mongo, but these days there are more specialized graph databases that excel at this kind of work and may be much easier for you to use, especially on large graphs. There is a comparison of 7 such …
graph rendering in python (flowchart visualization) [closed]
Graphviz is the best option in my opinion. Graphviz is the premiere graph rendering/layout library; it’s mature, stable, open-source, and free of charge. It is not a dedicated flowchart or diagramming package, but its core use case–i.e., efficient and aesthetic rendering of objects comprised of nodes and edges, obviously subsumes flowchart drawing–particularly because its api …
How to create charts using NodeJS?
d3 is probably your best bet. It can generate nearly any type of chart imaginable. You can generate the charts directly in the browser, or if you really need an image file, you can use the module in node and convert the output to an image.
Set Colorbar Range
Using vmin and vmax forces the range for the colors. Here’s an example: import matplotlib as m import matplotlib.pyplot as plt import numpy as np cdict = { ‘red’ : ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)), ‘green’: ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)), ‘blue’ : ( (0.0, …
Longest word chain from a list of words
You can use recursion to explore every “branch” that emerges when every possible letter containing the proper initial character is added to a running list: words = [‘giraffe’, ‘elephant’, ‘ant’, ‘tiger’, ‘racoon’, ‘cat’, ‘hedgehog’, ‘mouse’] def get_results(_start, _current, _seen): if all(c in _seen for c in words if c[0] == _start[-1]): yield _current else: for …
Modifying vertex properties in a Boost::Graph
Bundled properties are straightforward to use: using namespace boost; struct vertex_info { std::string whatever; int othervalue; std::vector<int> some_values; }; typedef adjacency_list<vecS, vecS, undirectedS, vertex_info> graph_t; graph_t g(n); g[0].whatever = “Vertex 0”; […] and so on. Please also refer to the docs. The other type of vertex property that are very useful are external properties. You …
How do I visualize social networks with Python
networkx is a very powerful and flexible Python library for working with network graphs. Directed and undirected connections can be used to connect nodes. Networks can be constructed by adding nodes and then the edges that connect them, or simply by listing edge pairs (undefined nodes will be automatically created). Once created, nodes (and edges) …
How to draw a surface plot without black edges in MATLAB?
Another choice is to set the edgeColor and/or lineStyle properties of the surface handle object to none. >> hSurf = surf(X,Y,Z,’EdgeColor’,’none’,’LineStyle’,’none’,’FaceLighting’,’phong’);
