What is a bubble chart?
Many datasets contain two or more quantitative variables. You may be interested in how these variables relate to each other. To plot the relationship of just two such variables, usually you use a scatter plot. If you want to show more than two variables at once, you may opt for a multidimensional bubble chart.

Bubble Chart: What's new?
NEW Most of our data visualisations now support SI prefixes, advanced number format options for axes and shown data labels.
Easier number formatting through some changes in the user interface. Showing and hiding values is possible in the same place as you format them.
We added an option to hide axis labels.
We improved the sorting for an even smarter chart. Bubbles will be rendered by their size: largest on bottom, smallest on top so you won’t miss any observation.
NEW You can now display bubbles even if these represent negative values in your data. 🧐
NEW We added the possibility to set the minimum size and maximum size of all bubbles to your liking.
NEW We have also added an option to customize the opacity and the border width.
NEW It’s now possible to hide all labels by just one click.
And generally, we improved the overall performance of the chart.🎈
