Question 17
Answer:
In order to improve the Espléndido Jugo y Batido data dashboard, firstly I would change
the color scheme. The yellow background is too bright and causes eye strain. Some neutral
background colors like gray or white would be appropriate to focus on the visualization.
Secondly, the layout seems cluttered degrading the readability. The font choice can be
considered, and the size can be increased too. Along with that, some interactivity like filters or
tooltips could allow users to explore the data more deeply. Implementing these changes would
enhance the dashboard’s usability, readability, and overall effectiveness in conveying
information.
Question 18
Answer:
Some improvements were made to the yellow dashboard. However, there are still some
improvements that could enhance its effectiveness. The dark blue background is better than the
yellow one but a lighter neutral color would decrease the eye strain and improve readability. A
pie chart is not recommended for data visualization so it could be replaced with some other chart.
Some filter controls can be used for interactivity too. The font can be changed to some readable
sans serif font. These changes could further improve the dashboard’s viewing experience.

Question 19
Answer (a):
For improving the Espléndido Jugo y Batido data dashboard, I recommend using scatter
plots to show the relationship between average service and product satisfaction ratings across
distribution centers for each of the past three years. This is because scatter plots effectively
visualize correlations between two variables and allow easy comparison across years. Along with
that, we can identify high and low-performing distribution centers.
Answer (b):
To incorporate these changes, we should resize existing charts to make room for a new
section with three scatter plots (one per year) and a table showing satisfaction ratings by
distribution center. The dashboard should be made interactive using filters and tooltips, use
consistent colors, and include brief explanatory text. The dashboard title should be updated to
show the new data. These changes would ensure effectiveness in the dashboard.
