Now it's your turn to explore. The line graph above shows the number of coronavirus cases or deaths over time for one of five Texas counties with the highest populations: Harris County which includes Houston, Travis County which includes Austin, Dallas County, Bexar County which includes San Antonio, and Tarrant County which includes Fort Worth. You may look at the coronavirus data for these counties from different perspectives: from picking a date range, county and dimensions (cases, deaths, new cases and new deaths). It is interesting to note that the y- and x-axis scales and tick marks will adjust according to the items selected in the controls. Hovering over the line graph itself would trigger a handy tooltip showing the value of the currently selected point in the graph. Can you answer the following questions using this tool?
