Leigh Hutsell DAT530 5-1 Exercise Presentation and Visualization of Data
AUDIENCE 1 – BUYERS New Chart type: Treemap Audience: Buyers. Visualization Style and Elements Chosen: I originally chose the donut chart in Unit 4 but changed to the treemap for Unit 5.

either of these dimensions. If our data is such that our audience needs to make precise comparisons between categories, it’s even more cumbersome when the categories aren’t aligned to a common baseline. We should never make our audience do more work than necessary to understand a graph!” (Ricks, E., 2018). AUDIENCE 2 – MANUFACTURERS Chart type: Waterfall Chart Audience: Manufacturers Visualization Style and Elements Chosen: The visualization I close originally was the table but I have changed to the waterfall chart. Where the table can be overwhelmed with data the waterfall chart shows a clear and simple structure and it transforms data well.
