Most data is meaningless to most people — unless it is visualized. Stepping beyond familiar visualizations like bar charts and pie charts, there are many approaches to visualizing data, from mapping (e.g., color coding a map to show voting patterns) to visualizing networks (e.g., the links between people).
You are not limited to Microsoft Excel, or your own programming abilities. We’re now in an awesome generation for visualization, with dozens of freely available software libraries — which developers have spent months (or years!) building. Increasingly these use Javascript (so they work in all browsers and mobile devices). The folks at Datavisualization.chhighlight most of the best tools for making maps and charts, or processing data…
