Packed Bubble Visuals

In Arcadia Enterprise, packed bubble charts compare the relative values in close physical proximity. We use two main series of data: the field on the Dimensions shelf names the bubble, and the field on the Measures shelf determines the relative area of the bubble.

Contrast this with the traditional approach, where bubbles represent three dimensions of data — one each for horizontal and vertical axes, and one for the area of bubble. This type of visualization is part of flexibility built into Arcadia's scatter charts.

The following steps demonstrate how to create a new packed bubbles visual representation on dataset World Life Expectancy [data source samples.world_life_expectancy].

Start a new visual based on dataset World Life Expectancy [data source samples.world_life_expectancy]; see Creating Visuals.
In the visuals menu, find and click packed bubbles (row 2, column 3).
Note that the shelves of the visual include Dimensions, Measures, and Filters.

The mandatory shelves for packed bubbles visuals are Dimensions and Measures.
Populate the shelves from the available fields (Dimensions, Measures, and so on) listed in the left navigation menu.
- Under Dimensions, select country and drag it over Dimensions shelf on the main part of the screen. Drop to add it to the shelf.
- Under Measures, select population and drag it over Y shelf on the main part of the screen. Drop to add it to the shelf.
On the Y shelf, on sum(population) field, click the icon (down arrow), select Aggregates, and then select Average.
Note that the Y shelf now contains the modified field avg(population).
Click Refresh Visual.

The packed bubble visual graph appears.
[Optional] On the Filters shelf, add several fields from Dimensions and Measures.
This enables you to dynamically control the data input, and discover the data at a more granular level.

For example, from Dimensions, drag year onto the Filters shelf.
On the Filter shelf, click the icon (down arrow) on the year field, and select Pick values from a list.
In the Pick values for year modal window, select 2010, and click Save.
On the Measures shelf, click the icon (down arrow) on the avg(population) field, select Order, and then select Ascending.
Click Refresh Visual to see the updated packed bubbles chart.
Click Edit next to the title of the visualization.
Change the title to World Population - Packed Bubbles.
Above the left navigation bar, click Save.
