Persona

• Provide 3 pieces of constructive feedback that could help the app to be better suited to the scenario it was designed for
• Provide 3 pieces of constructive feedback that could help the app to be better suited to the user(persona) it was designed for

Frontend / layout

• Is the text (plot labels / titles / subtitles) easy to read?
• Are the plots selected appropiated for the data? Can you think of other alternatives or improvements for the plots regarding interactivity/reactivity or plot selection?
• Was the dashboard organized in a way that was easy to read (columns / rows) or you would suggest a change in this sense?
• Would you prefer including tabs / navbars to improve the navigation or you think it is better to visualize everything in one screen by the nature of the content?
• Are the plots or other images described properly for the persona described?

Backend

• Are the options that you can select in the widgets working fine or have you found some cases where it is not working?
• If there are interactive plots: are the labels clear and easy to understand?

Documentation

• Was the documentation easy to understand from the README.md how to use the app? How could the documentation be improved?
• Was the app intuitive to use without reading the documentation? What information could be good to include?

Indicate something you would like to include in your own app after reviewing this one

Reviewer: Group 9

Persona

• Provide 3 pieces of constructive feedback that could help the app to be better suited to the scenario it was designed for

1. To analyze the trend over time of various COVID metrics, I believe an animated world map may not be the best suited visualization on the main page. Animated world map would be very effective during a presentation. But to draw insights the world map which shows data within a time range would have been more suitable. At certain periods there is no noticeable change in the color gradient and may not be very insightful.
2. In the study since we are comparing Canada's approach to the pandemic with the other countries, cases per million, deaths per million would be a more useful metric than the number of cases or number of deaths.
3. The plot names Current ICU Hospitalizations, Current Hospitalizations and New Vaccinations in the 3rd tab could be misleading as we are looking a trend over time. It could be replaced with 'Daily'.

• Provide 3 pieces of constructive feedback that could help the app to be better suited to the user(persona) it was designed for
  1. To draw insights from the animated world map could be difficult if the user is not sure of the date range. The global heat map itself with out the animation may be more intuitive. Also, the line plot is quite handy in this case.
  2. A note saying why different data scale for plots in second and third tab may be helpful.
  3. An easy way to help the user choose countries from dropdown. Say, a list of countries that could be of interest and would be useful to study could be grouped together rather the user trying to look at all the countries and come up with a list.

Frontend / layout

• Is the text (plot labels / titles / subtitles) easy to read? Yes, the titles, labels are easy to read.

• Are the plots selected appropriated for the data? Can you think of other alternatives or improvements for the plots regarding interactivity/reactivity or plot selection? Yes, all the plots selected are appropriate for the data.

• Was the dashboard organized in a way that was easy to read (columns / rows) or you would suggest a change in this sense? Yes, the dashboard is organized in a way that is easy to read and is very user friendly.

• Would you prefer including tabs / navbars to improve the navigation or you think it is better to visualize everything in one screen by the nature of the content? The dashboard had tabs and it was a good decision to organize the plots the way it is.

• Are the plots or other images described properly for the persona described? Yes, the plots are described properly for the persona described.

Backend

• Are the options that you can select in the widgets working fine or have you found some cases where it is not working?
• If there are interactive plots: are the labels clear and easy to understand?

All the widgets are working fine. The data fields are included in the tooltip for each plot and I found it very useful when looking at a data point and world map.

Documentation

• Was the documentation easy to understand from the README.md how to use the app? How could the documentation be improved? Yes, the documentation from README.md was easy to understand.

• Was the app intuitive to use without reading the documentation? What information could be good to include? Yes, the app was intuitive to use without reading the documentation. There are clear notes given explaining each widget and how to use it.

Indicate something you would like to include in your own app after reviewing this one I would like to include different metrics in the dropdown for the user to select and visualize. I would like to include tabs/nav bars for our dashboard. I believe it would give a nice flow to the content.
