The app visualization and functionality is straightforward and easy to understand. It can definitely help the analyst to understand the market better.

One thing I would like to point out is about the placement of the three graphs. As they are arranged vertically, I can hardly see the changes on the second and third graph when I change the filter inputs. One suggestion is to include a tab to separate the three graphs.

The choice of colors for the charts is effective as it helps differentiate different groups easily. However, it would be better to arrange different groups from highest to the lowest according to values.

The user input filtering widgets have been properly chosen based on the data set. The biggest confusion to me is the checkbox group for include all brands and include all categories. After checking the include all button, it is not intuitive to see if I have selected all the brands or categories because the select box does not change. To include an observeEvent in the shiny app can be helpful to solve this.

Overall I think Ha's app is great. I get right away what the visualizations are about. I only have a few minor suggestions:

1. For the first plot, it would be great if the title can clarify whether it is the total number of styles sold or the total number of units sold
2. I don't think the legend for the bar charts are necessary because we can see the labels clearly on the y-axis
3. The "include all" checkboxes don’t work with the filter boxes.
4. The average price plot would be more effective if the outliers are excluded. It is hard to see the difference in average price when the boxplots are all clustered at one corner
