Graphic Recording is all about communication. There's definitely an art to it. But it's so not about art! Knowing a few things from the art world can certainly help, though.
Look at the graphic recording above. There's barely any drawing in it - some generic buildings, a few arrows, and a star. That's it! This image is mainly text. And some of that text is even a bit sloppy.
Yet, the image has impact. The impact comes from a few bold words and the bright orange color. Even with a lot of text, there's a sense of movement and balance. Thanks to how things are arranged on the page (the composition).
Bad composition makes people uncomfortable. Good composition draws them in. That's why great drawing is not the secret to creating great visuals. Great composition is really where it's at.
This graphic recording was created while listening to a pre-recorded TED talk, using one black and one orange marker.
