7 Billion: How Did We Get So Big So Fast?

Dynamic Visualizations and Metaphors.

Sometimes a static graphic alone can’t tell the complex visual story hidden in your data. NPR has provided a great example in this video of how to use moving and animated elements to tell a story of how the world’s population has grown to 7 billion people. Watch as they use the flow of water to indicate births and deaths and color to separate each continent. You’ll notice they also shift between different visualization techniques to emphasize different elements of their story. For example, they use an Area Chart in order to show the world’s total population growth over time. When you’re visualizing your data, keep in mind that you may need separate visual representations for the different types of data you wish to share.
