In this lab, you'll practice some of the introductory skills for creating graphs using the NetworkX library introduced in the previous lesson. To do this, you'll create a graph to visualize users and businesses from yelp reviews.
In this lab you will:
- Create basic network graphs with networkx
- Add nodes and edges to networkx graphs
- Visualize network graphs with networkx
To start, import the data stored in the file 'Yelp_reviews.csv'.
# Your code hereNow, create an initial graph!
# Your code hereCreate a node for each user and each business in the dataset. Networks with multiple node types like this are called bimodal networks.
Optionally, go further by creating a list of colors for when you visualize the graph. If you do this, append the color "green" to your color list every time you add a user node and append the color "blue" to your color list every time you add a business node.
# Your code hereNext, iterate through the dataset and create an edge between users and the businesses they have reviewed.
# Your code hereFinally, create a visualization of your network. If you chose to color your nodes, pass the list of colors through the optional node_color parameter.
# Your code hereNice work! In this lab you created an initial network to visualize a bimodal network of businesses and yelp reviewers!
