District map - nice use of leaflet. I could see it being more useful if you had more districts on the same map. Looking for trends or differences across school districts. Or maybe overlaying it not just with district lines but incorporating a measure of median household income? Worse schools are in lower income districts? I have no idea if this is relevant to the target audience, but it's a thought
School explorer
- Why use the fill aesthetic in the bar plot? This just duplicates the info on the x-axis
- Clean up all the axis and tick mark labels. Make sure everything has meaningful and human readable labels
- For the Select Grade input, sort the values in a meaningful way. What is "KF" and "PH"? Do they inherently belong after 6 and before 7?
- The student performance plot is very unclear. Under what conditions should I actually see something here? I had to play around with the input values a lot to generate anything, and even then the graph contained no data.
- Okay, when I did get it to work I saw a grouped bar chart with values for "Advanced" and "Satisfactory". I presume everyone else failed the test? Might a proportional bar chart make more sense here, or do we really want to precisely distinguish between satisfactory pass and advanced pass?
Longer term suggestions
- Get away from the default ggplot2 theme. Go with something more minimal or even create a custom theme to "brand" your visualizations.
- Think about how the dashboard will scale to different screen sizes. For instance, the school explorer page had problems fitting all the widget boxes horizontally across the screen when I shrunk the window some. Anything you can do to dynamically adjust for this would be helpful, especially if you think users will view the app on a tablet or smartphone
