This tutorial is for the static version of the motion chart: the bubble chart. How to Make Bubble Charts Ever since Hans Rosling presented a motion chart to tell his story of the wealth and health of nations, there has been an affinity for proportional bubbles on an x-y axis. A bubble chart can also just be straight up proportionally sized bubbles, but here we’re going to cover how to create the variety that is like a scatterplot with a third, bubbly dimension. Bubble chart datasets need to contain a data array of points, each points represented by an object containing the following properties: { // X Value x: number, // Y Value y: number, // Bubble radius in pixels (not scaled). Just like a scatter chart, a bubble chart does not use a category axis — both horizontal and vertical axes are value axes. We're doing something special though. The proper way to size each bubble is by mapping the variable to the area of the bubble (not the radius, diameter, or circumference of the bubble). The x and y position represent the magnitude of two of the quantitative variables, and the area of the bubble represents the magnitude of the third quantitative variable. You may have more than one series of bubbles on a chart. There's an underlying system that underpins how ggplot works. Description A Bubble Chart is a multi-variable graph that is a cross between a Scatterplot and a Proportional Area Chart. So basically, geom_point(aes(size=size_var)) tells ggplot that we're going to be plotting points and the size of each point will be specified by the 'size_var' variable in our data frame. Scatter charts are a great choice: To show relationships between two numerical values. Bubble charts show the relatedness of three different sets of values. Additionally, we recommend setting the sizemode attribute: https://plotly.com/python/reference/#scatter-marker-sizemode to area. Like a Scatterplot, Bubble Charts use a Cartesian coordinate system to plot points along a grid where the X and Y axis are separate variables. A bubble chart requires at least three variables (columns) of data: one showing the size of the bubbles and two others showing the horizontal and vertical position of the points. Here’s the code to create a simple bubble chart in R. Does this seem complicated? When using this package, please pay attention to whether your computer is connected to the Internet. sizeref = 2. Here is an example using an abstract of the Gapminder dataset made famous through the Hans Rosling Ted Talk. Inside the function, we first indicate that the df.test_data data frame contains the data we want to plot (data=df.test_data). And size= is a parameter that allows us to manipulate the size of the points we're plotting with geom_point(). Create Split Packed Bubble Charts. The bubble chart is a variant of the scatterplot.
