I was reading The Truthful Art by Alberto Cairo. The book talks about principles on visualization and infographics. It relates well to designing a product.
These are some of my scribbles, I remember tweeting them as well.
1. Clarity and depth are paramount in infographics.
2. A data visualization is a display of data designed to enable analysis, exploration, and discovery.
3. It has to be customization for each person needs.
4. The greatest value of a picture is when it forces us to notice what we never expected to see.
5. Getting information as right as possible with clarity.
6. We should avoid self-serving bias.
7. We should be truthful and honest to our audience.
8. A graphic that is truthful, functional, beautiful and insightful has the potential of enlightening as well.
9. What you design is never exactly what your audience ends up interpreting. So reducing the misinterpretation is crucial.
10. We snap judge if we have the necessary knowledge for it or not.
11. Simplicity is about subtracting the obvious and adding the meaningful.
