Reexamining the unfold of COVID-19 utilizing DDX Bricks

As Domo’s director of knowledge insights, I get requested loads of questions on Domo merchandise. However, for no matter motive, there’s one product characteristic particularly that I get requested about probably the most: DDX Bricks.

DDX Bricks are information app templates that help you create low-code apps regardless of your technical expertise. However their attraction extends far past that. In addition they are a good way so that you can add some wow issue to your visualizations—and, in flip, inform extra compelling information tales.

Take, for example, the DDX brick-powered map immediately beneath, which reveals the unfold of COVID-19 within the U.S. over the primary two months of 2022:

By having loads of pre-built bricks to select from, DDX Bricks additionally decrease the barrier to creating your personal information app. Choose the brick you need, join up the info, and voila!—you have got a functioning information story to inform.

If you wish to change or tweak some issues within the brick, that’s straightforward to do, too. Typically the code is commented with what completely different variables are, which makes altering them easy—even in the event you’re not acquainted with the language.

Living proof: After I created my first DDX brick across the Tokyo 2020 Summer time Olympics, I had no expertise with JavaScript. But it surely didn’t matter; I had a pre-made brick that was straightforward to switch, so I may tweak issues such because the cycle time between modifications, the displayed date, and the cadence between date modifications.

However again to the COVID brick, which I created by modifying one other brick from the Domo Appstore. I hear lots about animated maps displaying modifications over time, so I made a decision to create a brick that reveals precisely that, utilizing COVID case information over time based mostly on seven-day transferring averages:

As you’ll be able to see, the map tells a reasonably fascinating story. Choose the metric you want to see (click on on the grey, funnel-shaped filter icon to get the filter bar after which choose the Vaccinations view) and it’ll dynamically change the properties of the visualization.

The dates will change to solely embrace the dates which have information for that metric. And the scales will change so that there’s a single scale for that metric for the entire timeframe of the info.

Taking part in via this map on the 2 completely different metrics is fascinating. After I take a look at the brand new case rely, I anticipate to see an enormous spike across the starting of COVID, representing the primary wave, nevertheless it doesn’t actually present up. The wave that got here via in the beginning of 2022 dwarfs the primary wave. Maybe if I used a log-scale it could higher present the smaller waves.

Trying on the variety of vaccinations, the most important wave was clearly at first, with smaller waves displaying up later, doubtless when boosters turned obtainable or different demographics turned eligible for the vaccines.

The “Domo on Information” staff is at present engaged on changing these DDX Bricks displaying maps over time into templates that will likely be obtainable within the Domo Appstore. After they’re accomplished, I’ll replace this publish, as properly.

Total, the method of writing them was fairly easy, and allowed me to inform an information story in a approach that I used to be not in a position to do earlier than.
