Alex Velez drives home a point:
Our current #SWDchallenge has been on my mind. For those who don’t know, we pose a different monthly suggestion for community members to build their data visualization and presentation skills. It could be a prompt to try a novel graph type, redesign an existing example, or practice a specific technique like chart animation. This month, data storyteller Simon asked us to consider whether data always needs to be communicated in a graph. Simon shares, “When you have just a number or two, writing the numbers themselves can be much more powerful than burying them in a table or graph and potentially losing the impact of the main number you’re looking to share.”
This statement came to mind when I reviewed a chart over the weekend. The chart I’m referring to is a bar graph displaying the weekly weight measurements of my dog, Nemo.
Click through for Alex’s argument. My take on the matter is that the point of visualization is to convey relevant information to your audience. If you can do that with a single word or a single number, you don’t need to go further.
