Using Rust to solve some real life graph problems.
This is a exercise to learn more Rust and also better understand graphs of data
in real life situations, and what it looks like to solve those problems with Rust.
To emmulate real life data of graphs, we will use the Divvy Bike Trips open source
data set. It includes a few key data points that we can turn into a graph.
Mainly the start and end _station_id data points. These gives us Nodes, along with
telling us these two Nodes are conncted together since someome road a bike inbetween them.
Also, even better, we have the time / duration of that bike trip.
This will allow us to explore weighted graph problems. Since we can say it
took x or y time to travel from one node to another node.
This is a real life data set and will allow us to ask interesting questions,
that hopefully we can use Rust to sovle, while at the same time working
on basic DSA skills.
