Two Alternatives to Using a Second Y-Axis

Two Alternatives to Using a Second Y-Axis

Almost as often as I see a pie chart with a hundred tiny slivers, I see line graphs using two y-axes. And it is just as bad. Graphs like this appear in every industry, everywhere I consult all around the globe. Using two y-axes is not a great idea because it gets confusing, fast. Which line […]

Data Nerd Holiday Swag

One of the smartest branding moves is to keep yourself top-of-mind with clients when you aren’t in the throes of discussing contract details. The new year is a perfect opportunity to remind your clients that you are both fun AND serious about data. I send a holiday card to my clients every year and I […]
Qualitative Chart Chooser

Qualitative Chart Chooser

Hi. Hey there. Having a rough day? I have something to make it a little brighter. It’s my associate, Jennifer Lyons, with a qualitative chart chooser. ———————————- Visualizing qualitative data is like making homemade risotto.

Election Night Trap Map

Election Night Trap Map

Since none of us can escape election coverage, no doubt you’ve seen voter and poll data displayed on some unusual maps. 538 is showing electoral votes as a hex map (made up of hexagons) and the Wall Street Journal did the same as a tile map (made up of tiles, or squares). The general idea […]

Chart Chooser cards are simple and easy to use. They help you choose the best type of chart to display and format your data. Each chart card shows you the common name of the chart type, a description, a visual example, when it is used, and what type of data set it’s best for. The […]
Strong Titles Are The Biggest Bang for Your Buck

Strong Titles Are The Biggest Bang for Your Buck

If you do nothing else to improve a weak visualization, you’ll still seriously improve its interpretability by giving it an awesome title. Generally we use weak titles that don’t really tell us the point of the visualization: I think this is because we make our graphs in Excel, which pops in the two-word “Chart Title” […]

Now Open: Evergreen Data Visualization Academy

Four years ago today, I took the leap from salaried employee to independent consultant. Since then, I’ve worked with scores of organizations to help them use their data as a tool to change culture and become a communication powerhouse.

Make It A Game

Make It A Game

I spend a lot of time talking about really serious data with incredibly focused people. I love them and I love my job. But sometimes I need to balance that out with some Lucky Charms. So while eating my bowlful of magically delicious sugar bombs the other day and looking at the back of the cereal […]
