How to Make Animated (GIF) Heatmaps in R
Using color as the visual encoding, show changes over time in two dimensions.
How to Make an Interactive Map of Geographic Paths
With latitude and longitude coordinates, there are a number of ways to map geographic data using D3.js and Leaflet.
How I Made That: Animated Difference Charts in R
A combination of a bivariate area chart, animation, and a population pyramid, with a sprinkling of detail and annotation.
How to Make Frequency Trails in R
Also known as ridgeline plots, the method overlaps time series for a 3-D-ish view of the data. While perhaps not the most visually efficient, the allure is undeniable.
How to Make an Animated Pyramid Chart with D3.js
Compare distributions side-by-side with a pyramid chart. Observe the change over the years by animating it.
How to Make a Tiled Bar Chart with D3.js
Show individual data points by splitting bars into smaller cells.
How to Make Better-Looking, More Readable Charts in R
Defaults are generalized settings to work with many datasets. This is fine for analysis, but data graphics for presentation benefit from context-specific design.
How to Visualize Ranges of Data in R
When you want to focus on the magnitude of differences between low and high values, use visual cues that highlight distance.

Moving your data from the digital screen to something more physical isn't as tricky as it seems. Here's how I did it.
How to Make Chord Diagrams in R
Show connections in the circular layout for a more compact presentation.
How to Make Unit Charts with Icon Images in R
Make the unit chart less abstract with icons that represent the data, or use this in place of a bar chart.
How I Made That: Animated Square Pie Chart
Also known as waffle charts. Using animated transitions between values, you can allow for comparisons between categories.
How to Make Venn Diagrams in R
The usually abstract, qualitative and sometimes quantitative chart type shows relationships. You can make them in R, if you must.
How to Make a State Map Grid with Small Multiples in R
Combining small multiples with the grid layout can make for an intuitive geographic reference.
