The data being worked in the first submission was about Car Insurance Policy, which dataset can be found in ‘Data World’ under the category ‘Real World Fake Data’.

Figure 1. Full dashboard with navigation buttons in the first submission

Figure 1 shows the dashboard in the first submission. In the first submission, the created visualisation contains more than 10 navigation buttons as they were deemed necessary to access all insights from the provided data. In addition, several wordy paragraphs were written as an attempt to enable viewers in getting insights more efficiently. Furthermore, multiple charts were made to compare performance of different metrics.

After re-evaluating the dashboard, several flaws were discovered in the dashboard. First, the usage of navigation buttons can confuse the viewers as they need to jump into different tabs when collecting their insights. Next, putting wordy paragraphs may also confuse viewers as the information in the paragraphs may not suit the insights that they are trying to get. Lastly, the static graphs give inflexibility to obtain additional insights.

Hence, the dashboard was revised in accordance with visualisation best practices. The revised dashboard can be accessed via the following link: https://public.tableau.com/app/profile/kristiadi.uisan/viz/20220805Makeover1/FinalDashboard

Major revisions

Combining charts

After a week of learning, we learned about how junk charts can easily confuse the readers. Hence, it can be useful to summarise multiple charts into one. Condensing multiple charts can be done through setting parameters and putting multiple columns in one chart. Some examples of this practice are demonstrated in the following figure. Improvements can be observed between figure 2 and figure 3. While figure 2 contains multiple bar charts, only one bar chart with a reference line can be seen figure 3.

Restructuring dashboard

The other objective of revising the dashboard is to give a new dashboard structure which can better aid the viewers in getting the information they seek. While the first submission used navigation buttons, the revised dashboard was using filters and parameters which are more user-friendly for viewers. Furthermore, the revised dashboard also removed some charts which may not be relevant to the goals of the dashboard and charts which can be misleading. Illustration of the dashboard restructuring can be seen in figure 4.

While this revised dashboard still has some rooms for improvements, it is still an upgrade compared to the first visualisation as restructuring the dashboard can significantly reduce the viewers’ time in gathering insights from the visualisation.
