Learn to visualize your data like an expert with these practical how-tos for presentation, analysis, and understanding.

#### How to Make (and Animate) a Circular Time Series Plot in R

Also known as a polar plot, it is usually not the better option over a standard line chart, but in select cases the method can be useful to show cyclical patterns.

#### How to Make a Semicircle Plot in R

It's the half cousin of the bubble plot with less overlap and more straight edges.

#### How I Made That: Interactive Beeswarm Chart to Compare Distributions

The histogram is my favorite chart type, but it's unintuitive for many. So I've been using the less accurate but less abstract beeswarm.

#### How I Made That: Searchable Time Series Chart

When there are too many options or categories, it can be helpful to make the data searchable.

#### How to Make a State Grid Map in R

Something of a cross between a reference table and a map, the state grid provides equal space to each state and a semblance of the country to quickly pick out individual states.

#### How to Make Animated Line Charts in R

Sometimes it's useful to animate the multiple lines instead of showing them all at once.

#### How to Make a Multi-line Step Chart in R

For the times your data represents immediate changes in value.

#### Symbols-based Unit Charts to Show Counts in R

Add visual weight by using individual items to show counts.

#### Introducing a Course for Mapping in R

Mapping geographic data in R can be tricky, because there are so many…

#### How to Edit R Charts in Adobe Illustrator

A detailed guide for R users who want to polish their charts in the popular graphic design app for readability and aesthetics.

#### How to Make an Animated Map in R, Part 4

In the the last part of the four-part series, you make a longer animation with more data and annotate.

#### Transitioning Map, Part 3: Animate Change Over Time

How to make a bunch of maps and string them together to show change.

#### Transitioning Map, Part 2: Refining the Format and Layout

How to make a more readable and more visually accurate map, before you dive into the big transitions.

#### Transitioning Map, Part 1: Mapping Irregular Data with Interpolation in R

Rarely do you have evenly-spaced data across an entire geographic space. Here is a way to fill in the gaps.

#### How to Visualize Proportions in R

There are many ways to show parts of a whole. Here are quick one-liners for the more common ones.

#### How to Make Beeswarm Plots in R to Show Distributions

Try the more element-based approach instead of your traditional histogram or boxplot.

#### Make a Moving Bubbles Chart to Show Clustering and Distributions

Use a force-directed graph to form a collection of bubbles and move them around based on data.

#### How to Make Square Pie Charts in R

Instead of traditional pie charts that rely on angles and arc lengths to show parts of a whole, try this easier-to-read version.

#### Annotating Charts in R

Let the data speak for itself they say. That doesn't work a lot of the time, and when that happens, you need to explain.

#### A Course for Visualizing Time Series Data in R

Learn to visualize temporal patterns in a couple of days.

#### Drawing Circles and Ellipses in R

Whether you use circles as visual encodings or as a way to highlight areas of a plot, there are functions at your disposal.

#### Drawing Squares and Rectangles in R

R makes it easy to add squares and rectangles to your plots, but it gets a little tricky when you have a bunch to draw at once. The key is to break it down to the elements.

#### Voronoi Diagram and Delaunay Triangulation in R

The

`deldir`

package by Rolf Turner makes the calculations and plotting straightforward, with a few lines of code.
