Instructions
The assignment is to create a dashboard of two or more charts designed to visualize the data necessary to answer one or more questions about the data.
Required Elements
show a dashboard that includes the following two elements:
· Multiple charts (at least two) displayed simultaneously on the same screen at the same time.
· The ability to provide details on demand in at least one of the charts.
· The ability to support cross filtering between the two charts.
This dashboard shows a scatterplot on the left with each datapoint indicating life expectancy vertically and population horizontally, and the right is a simple geographic plot of the counties colored by region.
Notice the color scheme is consistent between the plots so that the datapoints in the left chart match the colors used for regions on the right so that regional trends can be seen in clusters on the left.
The layout is a simple 50-50 left-right since there are no similarities in the axes of the two plots.
As shown below, we can answer the question: which countries have the highest average life expectancy by selecting life expectancy over 75 years on the left and observing the highlighted countries on the right. Notice also this nicely demonstrates cross-filtering. (More on cross filtering in Tableau here.) Also, each datapoint in the scatterplot on the left has a popup that displays further details on demand when the mouse is placed over the datapoint.
Review Criteria
Your dashboard will be graded using the following rubric, with point values in brackets.
· [10] Providing a proper URL to the dashboard, and the dashboard appears at that URL without any further user intervention.
· [30] What is one question that the dashboard can answer by utilizing two or more simultaneously displayed charts? What is the answer? How do these two charts indicate the answer? (Spend some time to make sure you have picked a question whose answer is not simply given by just one of the charts, and the combination of the two charts gives a complete answer.)
· [10] Upload a screenshot of your dashboard answering that question by showing two or more simultaneously displayed charts.
· [20] How does the layout of these charts promote visual understanding of the data across multiple charts? Do the charts follow a consistent color scheme and are they well aligned with each other to promote better visual comparisons.
· [10] Indicate which chart should be graded as a “first” chart. Then justify the choice of this chart type, its axes and marks based on the data variables it shows.
· [10] Indicate which chart should be graded as a “second” chart. Then justify the choice of this chart type, its axes and marks based on the data variables it shows.
· [10] How does your dashboard provide details on demand?
· [10] How does your dashboard support cross-filtering between these two charts?
