Leveling up

This week’s infographic is a design about child development. I wanted to create a easy-to-read guide that would be helpful for both medical students and new parents. The infographic has a quick summary of each developmental milestone on the right panel, and a more in-depth numbered overview on the left panel. The goal was to make a chart that would be both useful and visually interesting.

Since a lot development milestones depend on earlier skills, I decided to stack each skill onto all of the previous ones in a waterfall-style area graph. To make this design I first organized each of the child-development milestones and picked a gradient of colors to match each category (process images are shown above). Then I made a custom timeline and cut each milestone color line at the correct time point. Finally I shifted each of the timeline colors to the center so that the entire design looked like a waterfall. I debated for a while where to put the detailed descriptions for each development stage, but I finally settled on a left sidebar to keep things less cluttered in the main section.

One of the unique customizations of this design is the nonlinear timeline. A third of the developmental milestones happen within the first 12 months, and increasing the spacing for the first few years helped emphasize these earlier years of development.

As with my other medical infographics, Dr. Arun Mathews, a Chief Medical Officer in Texas, fact-checked my work and suggested useful articles.


Heartbeats and murmurs

This week’s Nerdcore Medical collab is a paired poster for October’s Hearbeats and heart attacks poster. The last poster showed the EKG wave patterns of 10 different heart conditions, as well as the different parts of a normal EKG wave. This new poster shows the PCG patterns of 11 more heart-related diseases.

EKG waves (also called an ECG) shows the heart’s electrical activity, while a PCG uses a phonocardiograph to plot the sounds produced by the heart. So even though these two posters are made with similar design styles and fonts, the waves look completely different.

Since PCG waves can be a little more hard to decipher as a graphic, I replicated each wave three different times to show the various sections of the sound waves. The first heartbeat graphic shows just the S1 and S2 parts of the PCG wave. The second shows the S1 & S2 combined with the PCG systole sound, and the third wave illustrates the entire sound wave. I also included a small heart illustration showing the anatomical defects that cause each of the different diseases in the infographic.


Mind the pharmaceutical gap, please

This week’s medical infographic poster explains the possible side effects of prescription drugs. Since most of the side effects were specific to an organ system, I decided to make a London tube map of the body with “stops” for each of the different diseases.

This poster was a great excuse to buy the official London Underground font, which I’d wanted for a while. Unfortunately this ended up being more of a hassle than I anticipated. It was totally worth it to get the authentic font for the poster, but at the time the font had an undisclosed bug where you could only type the period character in the bold version. This was patched a few months later, but for this project I had to spend an hour going through the poster and changing every single period to a different font.

Other than the font issue this was a great project to work on, and I loved getting a chance to use the iconic color and typography of the London Underground. I switched from a white to navy background halfway through, and although this isn’t an exact replica of the original style I think the navy looks better as a poster.
