Reexamining the spread of COVID-19 using DDX Bricks

As Domo’s director of knowledge insights, I am getting asked lots of questions about Domo products. Alternatively, for regardless of purpose, there’s one product serve as specifically that I am getting asked about some of the: DDX Bricks.

DDX Bricks are knowledge app templates that may allow you to create low-code apps without reference to your technical experience. Alternatively their enchantment extends some distance previous that. Moreover they’re a great way to be able to upload some wow factor for your visualizations—and, in turn, tell additional compelling knowledge stories.

Take, for example, the DDX brick-powered map right away underneath, which reveals the spread of COVID-19 inside the U.S. over the main two months of 2022:

By way of having lots of pre-built bricks to choose from, DDX Bricks moreover lower the barrier to making your own knowledge app. Make a selection the brick you wish to have, sign up for up the guidelines, and voila!—you may have a functioning knowledge tale to tell.

If you want to alternate or tweak some problems inside the brick, that’s easy to do, too. Most often the code is commented with what completely other variables are, which makes changing them simple—even when you’re no longer conscious about the language.

Case in point: Once I created my first DDX brick around the Tokyo 2020 Summer time Olympics, I had no experience with JavaScript. However it didn’t topic; I had a pre-made brick that was once easy to switch, so I would possibly tweak problems such since the cycle time between changes, the displayed date, and the cadence between date changes.

Alternatively once more to the COVID brick, which I created through editing one different brick from the Domo Appstore. I listen relatively a bit of about animated maps showing changes over the years, so I decided to create a brick that reveals exactly that, using COVID case knowledge over the years essentially in response to seven-day moving averages:

As you in all probability can see, the map tells a rather eye-catching tale. Make a selection the metric you need to look (click on on at the gray, funnel-shaped clear out icon to get the clear out bar and then select the Vaccinations view) and it’ll dynamically alternate the homes of the visualization.

The dates will alternate to only embody the dates that have knowledge for that metric. And the scales will alternate in order that there’s a unmarried scale for that metric for all the time frame of the guidelines.

Participating in by means of this map at the 2 completely other metrics is eye-catching. Once I check out the new case rely, I rely on to look a huge spike around the beginning of COVID, representing the main wave, then again it doesn’t in truth provide up. The wave that were given right here by means of first of all of 2022 dwarfs the main wave. Perhaps if I used a log-scale it will upper provide the smaller waves.

Making an attempt at the number of vaccinations, the biggest wave was once obviously to begin with, with smaller waves showing up later, most certainly when boosters grew to turn into out there or other demographics grew to turn into eligible for the vaccines.

The “Domo on Knowledge” body of workers is at the moment working on converting those DDX Bricks showing maps over the years into templates that could be out there inside the Domo Appstore. After they’re completed, I’ll change this publish, as successfully.

Common, the process of writing them was once slightly simple, and allowed me to tell a data tale in a implies that I was no longer in a position to do previous than.
