Good Visualization:

This visualization caught my attention immediately, probably because the image packs so much motion. It effectively tells the story of one whole baseball sequence starting from the pitch to the tagging of a runner. This sequence is broken down into 4 steps, explained on the right of the page, out of the way of the action. Each step has a title that clearly identifies the main theme of the step and is accompanied by a helpful image to reinforce our visualization of that step. The text, though detailed, is not overbearing and can be skipped because of the step's tagline. By showing multiple body positions of the baseball players, the visualization successfully captures the action of the whole sequence in one static image. This image makes readers feel as if they are actually watching one whole play in motion and even introduces the action of the game effectively to those unfamiliar with baseball. This image also reinforces the advantage of installing the new camera system by showing us a glimpse of the level of detail at which we can analyze the game.

Bad visualization

This visualization attempts to teach the proper technique to perform a hang clean. Unfortunately, the images are insufficient to demonstrate visually how to execute the lift safely. The hang clean is physically intensive and also potentially dangerous if done incorrectly. Failing to follow proper form and posture risks serious back damage. This column offers only 2 snapshots out of a series of motions, thus failing to ensure that readers know the correct body positions during the lift.

Furthermore, the instructional text is quite dense when packed into one block. It is difficult to break the lift down step-by-step when all of the instructions are in one paragraph. The instructions should be separated from each other, broken apart into more than two steps, and accompany an image of the corresponding steps.

This technique is taught better by video.
