俗话说一图胜千言。但是“图”(Graph)说的远不止于此。以图形式呈现的数据可视化能帮助我们获得见解,并基于它们做出更好的数据驱动型决策。 但要真正理解图是什么以及为什么使用它们,我们需要理解一个称为图论(Graph Theory)的概念。理解它可以使我们成为更好的程序员。

To denote the length of the current shortest path from any given node to nodeA, we need to set "costs" for all nodes in the graph. All of the costs will be set toinfinityat the beginning, to make sure that every other cost we may compare it to would be smaller than the...
A simple python package for graph theory that supports multi-edges, hyper-edges, looped-edges and every other combination of these. - vaibhavkarve/multihypergraph
This chapter gives facts and theorems from linear algebra and graph theory that we use in the following chapters. We include a brief introduction to Python programming with further references for more extensive study. Python codes are provided to help you learn the basics and to give you a ...
