A bubble chart is a type of data visualization that displays three dimensions of data on a two-dimensional plot. Each data point in a bubble chart is represented by a "bubble," where: the X-axis represents one variable, the Y-axis represents a second variable and the size of the bubble (typically determined by its area or radius) represents a third variable. In Arbometa bubble chart is a preview action for a node. If you don't understand, what we are talking about, please check our about page.
Current example
We wanted to check dependence between GDP per capita, Gini index (measures how evenly income or wealth is distributed in a population) and education spending (% of GDP for every country) via bubble chart. We had several sources of data - GDP per capita, Gini index and education spending per country per year. We imported data, created bubble chart and generated the whole software automatically.
Bubble location on the left means, that particular society is more equal. Bigger bubble means higher GDP. Bubble location on the top means, that particular society spends bigger % of GDP on education. As to the results - seems, that society wealth depends on equality more than on education spending.

How we made this example
- We've created a node "GDP, Gini, education" with 5 fields: country, year, GDP, Gini and spending on education. How to create a node.
- Added a preview of bubbe chart type to the node.
- Added the year filter to the preview (filters explained).
- We had two files with data in CSV format (CSV format represents data as a table - you can open it in Excel, for example). In one file there were GDP and Gini index per country and year. In the second - % of GDP spent on education per country and year.
- Created two imports - one for each data file. (about data import and export).
- Automatically generated programming code.
- Imported data from the files.
- Made some minor modifications to the design.
