Here we visualize data from the Covid-19 spread in the US. To display the data you have to press the "Update" button. Once the button was pressed the stippling starts and when the process is finished the stippled representation of the selected dataset is displayed. Via the time slider at the top a date can be selected for which the Covid-19 related data are displayed. Note that the date has no effect on the population density stippling. For some dates, where there are very few cases the stippling may not perform optimally. This is due to the fact that the stippling approach is generally more suited for dense data.
