Circle packing customization with R

This posts explains how to build a one level circle packing chart with space between bubbles, improving the general appearance.

Circle Packing section Data to Viz

This chart is just a customisation of the chart #305 which describes the basic process to make a one level circle packing chart. I personally like to add a bit of space between each circle.

Basically, all you have to do is to reduce the radius size in your data once this one has been calculated. Just multiply it by a number under 0, and it will decrease the circle size.

If you have been so far, you probably want to check the interactive version of the chart !

# libraries

# Create data
data <- data.frame(group=paste("Group", letters[1:20]), value=sample(seq(1,100),20)) 

# Generate the layout
packing <- circleProgressiveLayout(data$value, sizetype='area')
packing$radius <- 0.95*packing$radius
data <- cbind(data, packing) <- circleLayoutVertices(packing, npoints=50)

# Plot 
ggplot() + 
  geom_polygon(data =, aes(x, y, group = id, fill=id), colour = "black", alpha = 0.6) +
  scale_fill_viridis() +
  geom_text(data = data, aes(x, y, size=value, label = group), color="black") +
  theme_void() +
