Interpretation: Cases on each day, with labels for each Monday (and other critical dates labeled). Given that the number of tests varies from day to day, focus on the overall trends rather than the absolute numbers (see the Average Cases graph below for a smoothed version).

Interpretation: The dark blue line and numeric values present a rolling 7-day average of the number of new positive cases. For example, the value for January 8 is based on an average of the number of daily cases between January 2 and January 8. The faint blue bars duplicate the bars from the Daily cases graph. The 7-day average smooths out the daily variability by averaging a full week’s values.
