Best Data Visualization Projects of 2020
I’ll be honest. I thought about skipping the picks this year. Then I felt that’s no way to finish up 2020. So, here are my favorite visualization projects in no particular order. Of course there was one topic that weighed most heavily, but there were also some other interesting works along the way.
Best Chart Loosely Based on Data to Demonstrate an Idea
Flatten the Curve
In the early part of March, we rallied around “flatten the curve”, because the healthcare system was going to buckle if we didn’t. We had to slow the number of people in the hospital at the same time.
Rosamund Pearce for The Economist made the first recent version. It was based on a graphic (pdf) by the Centers for Disease Control, all the way back from 2007. Other versions then popped up, including the animated version above by Alexander Radtke. It almost seemed like we were doing it for a while. [See the Project / On FlowingData]
Best Demonstration of Virus Spreading with Simulation
Why outbreaks like coronavirus spread exponentially, and how to “flatten the curve”
While we rallied around flattening the curve, it was clear that a lot of people didn’t know what that actually meant. For The Washington Post, Harry Stevens used a simulation of a simplified version of the virus to demonstrate. The curve became less of an abstract statistical exercise and more of a practical goal.

Best Visualization of Masks Working
Masks Work. Really. We’ll Show You How
With debate around the usefulness of masks, many took on the task of showing that masks are effective in slowing down the spread of the coronavirus. For The New York Times, Or Fleisher, Gabriel Gianordoli, Yuliya Parshina-Kottas, Karthik Patanjali, Miles Peyton and Bedel Saget put together this stellar piece zooming into the fibers of a mask.

Best Close-to-Real-Life Visualization of the Virus Spreading
How the Virus Got Out
By the end of March, more data was becoming available and it was growing more clear where the virus came from and how it spread. For The New York Times, Jin Wu, Weiyi Cai, Derek Watkins, and James Glanz traced the path back to the beginning. [See the Project / On FlowingData]
Best Compilation of Livestreams
Reconstructing seven days of protests in Minneapolis after George Floyd’s death
There were days of protests in Minneapolis, but it was difficult to know what was happening for those looking in from the outside. In a collaboration between Holly Bailey for The Washington Post and Matt Daniels and Amelia Wattenberger for The Pudding, live video streams were spliced together to lend some continuity. [See the Project / On FlowingData]
Best Traditional Chart Recurring Over and Over and Over and Over Again
The Line Chart
Have more line charts been published, looked at, obsessed over, and referenced in a single year ever?
We craved change. We wanted to see how things were getting better (but they got worse) over time. We wanted to compare against other time periods, other groups, and other geographies.
We saw change in customer visits to businesses; there was unemployment for different groups; there were charts showing excess deaths; and comparisons to the 1918 pandemic. There were many more. [The Line Chart On FlowingData]
Runner-up — Variable-width bar chart. It had a bit of a moment this year, but it was up against stiff competition.
Best Generated Map that Looks Like a Real Map
Best Use of Physical Object to Show Data
The California Pint
Best Abstraction of a Traditional Chart
Best Customizable, Single-task Map Tool Thing
Rewind back to January, a simpler time. Andrei Kashcha made a simple-to-use tool to make ridgeline maps of anywhere in the world. He followed that up with a tool to make street maps of anywhere in the world. [See the Project / On FlowingData]
The Covid-19 Data Behind the Charts
While not a visualization project per say, I argue that if there’s no data the chart dies. Data is part of the visualization. For whatever reason, some governments could not provide a reliable dataset to gauge how we were all doing. Thankfully there were sources like The COVID Tracking Project, the Johns Hopkins Coronavirus Resource Center, and Our World In Data. [See the Project / On FlowingData]

How to Make Frequency Trails in Excel
Also known as ridgelines, use the method to create a compact visualization where you can easily identify major patterns and outliers.
Making an Interactive Map with Category Filters
Let readers focus on the regions they care about to make their own comparisons and conclusions.
How to Visualize and Compare Distributions in R
Single data points from a large dataset can make it more relatable, but those individual numbers don’t mean much without something to compare to. That’s where distributions come in.
When Americans Reach $100k in Savings
It was reported that 1 in 6 millennials have at least $100,000 saved. Is this right? It seems high. I looked at the data to find out and then at all of the age groups.
A Day in the Life of Americans
I wanted to see how daily patterns emerge at the individual level and how a person’s entire day plays out. So I simulated 1,000 of them.
How to Spot Visualization Lies
Many charts don’t tell the truth. This is a simple guide to spotting them.
