Persona

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

  1. There is no plot for showing “Ratings”, as what is mentioned in the proposal, in your dashboard. Therefore, a selection area of “Ratings” can be added.
  2. You also mentioned the change trend of the rating, so a line chart can be created for this scenario.
  3. Adding a radio button or tab to select for movies/tv shows in the top directors graph like shown in the proposal could allow for better separation between the types of media

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

  1. Brief descriptions or instructions of each plot can be added to the dashboard to make the user understand better of the outcome.
  2. To better help audiences determine specific trends within time frames, changing the year slider at the top to a range slider could help audiences pin-point data within certain time frames.
  3. To improve clarity of the dashboard, it could be helpful to scale up the size of the bubbles in the Movie and TV shows produced by country graph to a proportion of the productions in the selected time frame. Currently, it the bubbles are generally quite small, and it can be difficult to pin-point or hover over.

Frontend / layout

• Is the text (plot labels / titles / subtitles) easy to read?

  • Yes, they are easy to read.
  • There is just a grammar mistake in the map title: the “movie” and “TV show” should use their plural form. Also, increasing the size of plot titles or assigning them their own header block would allow for even more clarity

• 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?

  • Yes, they are appropriate for the data.
  • For showing the trend of movies and series or displaying how they change over the years, I think a line chart can still be applied, which can show the “trend” in a more straightforward way. You can make it only update the line chart by selecting categories.
  • Another Idea could also be to have a graph showing the distribution of ratings of movies/tv shows for each particular year or by genre, that way the dashboard would have more actionable data for decision makers.

• Was the dashboard organized in a way that was easy to read (columns / rows) or you would suggest a change in this sense?

  • If there is an intention of allowing users to filter the directors graph in the future, it may be a good idea to incorporate a tab layout for both the directors graph and the duration of movies graph, that way there is one selector for both graphs and is more 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?

  • Since there are only three plots, I think it is better to keep all content in one screen, so that the users do not need to go to different places for different plots.
  • Tab navigation for the movie and TV show durations is appropriate here, since the graphs are showing different data on their X axis.

• Are the plots or other images described properly for the persona described?

  • Yes, the plots for the most part are described effectively and their titles/content are easy to understand for their intended audience, aside from minor typos mentioned previously.
  • The only slightly confusing area is the duration graphs in the bottom right with the duration of movies and TV shows measured in different units. Perhaps editing the titles to mention the unit of measurement could be helpful in improving clarity

Backend

• Are the options that you can select in the widgets working fine or have you found some cases where it is not working?

  • It is better to add category selection to the update of the map plot.
  • It seems like there are some missing values for duration, because when we select some TV shows, there are corresponding directors and the number of their productions coming out, but the TV Show plot does not show any data.
  • In the category list, movie and TV show genres are mixed which makes it harder for users to explore and select. Also there are categories called “Movies” and “TV Shows” in the same list. Users will get confused whether these two categories refer to the gathers of their corresponding categories or other kinds(of movies or TV shows).
  • More obscure genres seem to have very little data and may confuse the user since there will be nothing displayed on the graphs. A fix to this can be limiting the selection of genre to the top 20 genres to avoid empty graphs.

• If there are interactive plots: are the labels clear and easy to understand?

  • The labels are clear and easy to understand when putting the cursor on the selected area. For the “TOP 10 Directors…” plot, users can also click on it for highlighting, which makes the plot easier to read. We think you can apply this function to the other two plots as well.
  • Scaling up the size of bubbles in the movies produced worldwide plot would greatly help the interactivity of the plot, since currently it is very difficult to hover the circles as they are so small.

Documentation

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

  • It seems like the description of the dashboard has not been updated to the readme file yet.Since there is a big change of your dashboard sketch and the final outcome. I think you can either substitute the sketch part to the description of the current dashboard.
  • The description paragraph should be updated, like removing the words of “line chart” which does not align with the final dashboard.
  • A short video of displaying the dashboard and using instructions can be uploaded.
  • I think you can also add table content to the readme file which can make it easier for users to be navigated to the place they want to explore.

• Was the app intuitive to use without reading the documentation? What information could be good to include?

  • Except for the confusion of the map update with the change of category selection(see suggestion for Frontend/layout), most of the app is intuitive to use.
  • A line of clarifying the plot interactions can be added for users.

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

1. We want to add more aesthetics to our dashboard, like adding background and title colors, using cards for some sections for a better layout.
2. We may add more interactions to the plots, like showing the actual number of a selected area.
3. We can add a line to clarify that the Winter and Summer Games were held in the same year up until 1992(after that, they staggered them such that Winter Games occur on a four-year cycle starting with 1994, then Summer in 1996, then Winter in 1998, and so on). So our users can understand the “unexpected” change of plots when they select “All” for Olympic seasons, without going to our repo to read through the documentation.
4. We can limit the selection of our drop down lists and slider selections so that there are no cases where plots display no data to avoid any user confusion.
