Hi team, I really like this dashboard as it provides many insights into car sales in the US. For example, right when I opened the dashboard, I noticed there were peaks in car sales between 2004-2008 and in 2017. Additionally, there's been an exponential increase in the average car price. These insights are very interesting and should be useful to relevant stakeholders.

Here are my two cents for your consideration:

• Could the units (e.g. for vehicle numbers, for sales price) be clarified? At first glance, I thought the "Total Number of Sales" in the top left corner was in units, but then I realized it might be in thousands or millions. It would be helpful if the units were more clearly marked on all charts. #84
• The label on the legend of the map is not fully displayed (Number of...). #85
• In the three bar charts at the bottom, the middle chart uses different colors for different qualities, but the bars in the adjacent charts are all the same color. It might be more visually cohesive if the styling were consistent across these charts. #86
• For the "Distribution of Prices" chart's x-axis, is the maximum value is fixed at 400k? When I selected the Year Range from 2005-2020, the "Total Number of Sales" showed 27163, but the sum of the first four bars (27163, 556, 73, 28) only totals 27150, leaving a difference of 13 that I couldn't locate on the graph (perhaps it's too small and merged with the x-axis). The maximum value in the sidebar's Price Range is also 500k, thus I'm wondering if some data points are hidden? If the x-axis values could dynamically adjust and if each bar in the three plots had numbers labeled, it would be more user-friendly. #87

Overall, this dashboard is awesome and impressive! Well done!
