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 purpose, there’s one product characteristic specifically that I get requested about essentially the most: DDX Bricks.

DDX Bricks are information app templates that mean you can create low-code apps regardless of your technical expertise. However their enchantment extends far past that. Additionally 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, as an illustration, the DDX brick-powered map straight under, which reveals the unfold of COVID-19 within the U.S. over time:

By having loads of pre-built bricks to select from, DDX Bricks additionally decrease the barrier to creating your individual information app. Choose the brick you need, join up the info, 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 straightforward to do, too. Usually the code is commented with what completely different variables are, which makes altering them easy—even if you happen to’re not conversant in the language.

Living proof: Once I created my first DDX brick across the Tokyo 2020 Summer season Olympics, I had no expertise with JavaScript. But it surely didn’t matter; I had a pre-made brick that was straightforward to change, 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 rather a lot about animated maps exhibiting modifications over time, so I made a decision to create a brick that reveals precisely that, utilizing Covid case information over time exhibiting 7-day shifting averages:

As you may see, the map tells a reasonably attention-grabbing story. Choose the metric you wish to see (click on on the filter icon to point out the filter bar and 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.

Enjoying via this map on the 2 completely different metrics is attention-grabbing. Once 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. It doesn’t actually present up because the wave that got here via initially of 2022 dwarfs the first wave compared. Maybe if I used a log-scale it might higher present the smaller waves.

Trying on the variety of vaccinations, the most important wave was clearly to start with, with smaller waves exhibiting up later seemingly when boosters or different demographics grew to become eligible for the vaccines.

The crew is presently engaged on changing these DDX Bricks exhibiting maps over time into templates that might be accessible within the Domo Appstore. Once they’re accomplished, I’ll replace this publish, as properly. Total, the method of writing them was fairly easy, and allowed me to inform a knowledge story in a manner that I used to be not in a position to do earlier than.
