This chart shows how a $100 grocery basket (with the same goods tracked month-to-month, for example) would have changed price on average through a rolling 12-month period, as indicated by the numbers on Y-axis. If you hover over the data, you can see how prices have changed on average each month versus the prior month.
These charts also show how a $100 grocery basket (with the same goods tracked month-to-month, for example) would have changed price on average through a rolling 12-month period, but drilled down by retailer and category. If you hover over the data, you can see how each retailer and category has changed each month versus the prior month.
How do you read this chart?
A bubble plot is used to look at relationships between multiple numeric variables, simultaneously.
In this case, each dot corresponds with the last month’s price and product availability changes within a particular grocery categories at a specified retailer. The bubble size indicates how much greater or smaller the change is compared to other retailers within the same category and across categories within the same retailer.
