Purpose & Application¶
The bubblechart is perfect for benchmarking across 3 dimensions.
It allows you to connect three indicators, to illustrate correlations. It I perfect and adapted to compare complex sets.
📝 For example, I want to compare my Business units across sales, margin and market share
Use the axis for the 2 most important metrics and the size of the bubble for the last one.
Bubblecharts are generally used to compare and show the correlation between labels and categories, through the use of positioning and proportions. So, you can use the bubble chart to analyze patterns / correlations.
The use of too many bubbles can make the reading of a graph difficult. It therefore means that the chart has a limited data volume capacity. However, this can be overcome by interactivity: clicking on bubbles can reveal hidden information and getting in-depth details. It’s what we call drill
What makes this chart a killer story?
Easy to configure zones makes it easy to identify best/worst performer without even reading the axis 💯.
Nothing better than a color code to immediately understand your data. Think about the Growth–share matrix or the BCG matrix :)
📝 For example, I want to compare football player in Ligue 1 and determine who is the best based on 3 criteria : goals scored, average notation per match, and starting games
Smooth drill functionality to get a deeper level of analysis 🔎.
As a Business Unit manager, I want to know how the entities are contributing to the BU’s global performance.
Colors to identify ensembles in the chart among the bubbles 🎨.
For instance, in our case, Business Units of the same continent are in the same color.
