Reexamining the unfold of COVID-19 utilizing DDX Bricks

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

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

Take, as an example, the DDX brick-powered map immediately beneath, which exhibits 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 information, and voila!—you might have a functioning information story to inform.

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

Working example: After I created my first DDX brick across the Tokyo 2020 Summer Olympics, I had no expertise with JavaScript. Nevertheless it didn’t matter; I had a pre-made brick that was simple to change, so I might tweak issues such because the cycle time between adjustments, the displayed date, and the cadence between date adjustments.

However again to the COVID brick, which I created by modifying one other brick from the Domo Appstore. I hear quite a bit about animated maps exhibiting adjustments over time, so I made a decision to create a brick that exhibits precisely that, utilizing COVID case information over time primarily based on seven-day transferring averages:

As you possibly can see, the map tells a reasonably attention-grabbing 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 information.

Taking part in via this map on the 2 totally different metrics is attention-grabbing. After I take a look at the brand new case depend, I count on to see an enormous spike across the starting of COVID, representing the primary wave, however it doesn’t actually present up. The wave that got here via initially 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 largest wave was clearly to start with, with smaller waves exhibiting up later, probably when boosters grew to become obtainable or different demographics grew to become eligible for the vaccines.

The “Domo on Information” staff is presently engaged on changing these DDX Bricks exhibiting maps over time into templates that might be obtainable within the Domo Appstore. Once they’re accomplished, I’ll replace this put up, as effectively.

General, the method of writing them was fairly easy, and allowed me to inform a knowledge story in a means that I used to be not capable of do earlier than.
