Calculating the path between two countries with the least border crossings.

This repository shows some examples of:

• Consuming CSV data and building multiple graphs
• Displaying graphs with networkx/matplotlib.pyplot
• Finding the shortest path (Breadth-First Search) between vertices (e.g. France to China)
• Building a graph of all the non-islands of the world

The shortest path between France and China

fr-to-cn.py builds multiple graphs and dynamically outputs:

France is connected to 8 countries.
They are Andorra, Belgium, Germany, Italy, Luxembourg, Monaco, Spain, Switzerland.
The shortest path from France to China is: France -> Germany -> Poland -> Russian Federation -> China.

and displays:

The non-islands of the world

non-islands.py builds the same graphs, culls the islands, and displays:
