Using imagery to show people something that may be important… that’s a good idea!
Cheesing out and making very few images and then showing people the same image when the data falls into a range? Not as helpful.
How much battery do I have left in each of these images?
That went from 93%, which should look “nearly full” to 62%, which should look about half full. But the same image was used for this whole range. At a glance, I may think my battery life is seriously compromised when it’s still ninety-something percent.
Bad, bad data vis.
PS: White text on light green = hard to read, especially at a glance… and especially for color blind people.
