Nice work! The dashboard is very effective.

• It follows the "Purpose-driven dashboards" principle. Each tab/plot answers one research question. All research questions were chosen appropriately and well answered by the dashboard.

• All plots have default initial states to avoid over-plotting, as the "Choose defaults wisely" principle suggests.

• I found the dashboard instruction very concise and easy to understand, following the "Less is more" principle.

• The dashboard follows the "Allow users to filter data" principle and allows users to filter data with a dropdown menu or a slider. This feature makes it possible for users to interactively visualize the data.

I also noticed a few changes could be made to improve the dashboard.

• Parts of the instructions are hidden by plots. For example, in the first tab, the first "S" of the sentence "Select a statistic:" is hidden by the plot, not sure if this is a problem with my browser though. This could be avoided by adjusting the size of the plot or moving all menus or sliders to the top.

• The legend for the dashed line in tab 2 and tab 3 could be easily overlooked since it is separated from other legends. If possible, it is better to align the dashed line legend along with other legends.

• The interactive feature is not enabled in plots. I personally prefer the interactive feature and think that this feature makes the visualization more effective and helps users better explore the data.
