In the TED Talk: The beauty of data visualization, David McCandless talks about how visualizing data can be compared to building a landscape. The viewer must be able to read the data presented like a map, with easy directions and guidelines. He also uses the phrase "data is the new soil." He explained that data is a ubiquitous resource that can be used for many types of new information and insights. This data gets irrigated by networks and connectivity. The data visualization and infographics that result from this is compared to flowers blooming.
In the data visualized here, David McCandless explained this balloon-like data. Those at the top of the picture are ingredients in a study that provide conflicting evidence. As the viewers' eyes go lower, they see that the balloons become lighter in color, indicating lesser evidence within the study, based on the size of the ingredients. It was a very unique way to present data, allowing the viewer to clearly understand the visualization.
