Avoid more than 4 lines in a chart. Line charts are typically used to show trend over time. If possible, put labels near line rather than use a legend.

Most deception is unintentional, which means individuals must be very intentional in the data they are displaying.

When displaying data to be used to make significant decisions…be very explicit. In this case the data was used to make decisions about reopening the state.
