Data visualization is the process of taking some of the data, the numbers produced by our ever-computing technical world, and creating pictures from them to make sense of them. The pictures show the patterns, the trends, the relationships as visual elements so we can see them. The video describes the basic methods to create simple charts, some of the rules and caveats, and how these can also be made even more friendly and accessible to a non-technical audience. Making sure the data is useful and truthful, ensures the visualizations are useful and truthful.
The talk covers the most basic charts and how they are created, and their uses. It covers some of the mistakes which are easily made, and the most useful elements to be included – such as color and icons.
