Visualization Velocity
Velocity is all about the speed at which data is coming into the organization. The ability
to access and process varying velocities of data quickly is critical. A correlation matrix
combines big data and fast response times to quickly identify which variables are related.
It also shows how strong the relationships are between variables.
A correlation matrix combines big data and fast response times to quickly identify
which variables among the millions or billions are related. It also shows how strong the
relationship is between the variables.
Tell a Story
All good stories have a beginning, middle, and end. Data visualizations deserve the
same treatment. At the beginning of the visualization, introduce the problem or business
hypothesis. From there, back it up with data. Finally, end the visualization with a conclusion.
Visualize the Hook
Every good visualization has a hook or primary take away that establishes the theme.
As a designer, you should make this hook the focal point of the design if possible. Placing
the hook at either the center or very end of the visualization is usually best, since this will
get more attention. Give the most important information the most visual weight so that
viewers know what to take away.
