Tools
I used the igraph library in R to build this supply chain network.
Procedure
- The csv file nodesAndLabel was used to create the vertices (nodes)
- The csv file shipsAndConsignRelation was used to create the edges (links)
- I created a numerical representation of the node labels (1 = shipper, 2 = consignee)
- I color coded the nodes based on their labels and created a legend
- I set the edge width as 1.5*total.qty (total quantity of goods shipped) to visualize the "magnitude" of the shipper-consignee relationship
- I set the vertice width as 2*degree to visualize the number of relationships each entity was involved in
- To combat clutter, vertices were labeled based on the ID column instead of their company name
Assumptions
I assumed that the unnamed column in the nodesAndLabel file was some sort of numerical identification for the shippers and consignees. I also assumed that whoever would be using this graph would be familiar (or have easy access to) with the IDs.
