The purpose of visualization is insight, not pictures.
Numbers have an important story to tell. They rely on you to give them a clear and convincing voice.
There is a magic in graphs. The proﬁle of a curve reveals in a ﬂash a whole situation — the life history of an epidemic, a panic, or an era of prosperity. The curve informs the mind, awakens the imagination, convinces.
―Henry D. Hubbard
Visualizations act as a campfire around which we gather to tell stories.
The art and practice of visualizing data is becoming ever more important in bridging the human-computer gap to mediate analytical insight in a meaningful way.
By visualizing information, we turn it into a landscape that you can explore with your eyes, a sort of information map. And when you’re lost in information, an information map is kind of useful.
The goal is to turn data into information, and information into insight.
Above all else show the data.
The greatest value of a picture is when it forces us to notice what we never expected to see.
If someone is going down the wrong road, he doesn’t need motivation to speed him up. What he needs is education to turn him around.
