For this month's #SWDchallenge, we're not focusing on a specific chart type, but rather on a data type: bespoke data. A dataset that you collected yourself—electronically, manually, via surveys, by observation…whatever you like, as long as it is yours and yours alone.
Go out and collect a dataset of your own, analyze it and create a graph visualizing your findings.
Data was exported from Mint.com after being filtered for all Food & Dining expenses.
