“The goal of Data Visualisation is to deliver insight.”
In fact, that is the whole point. Insight – about your data. You can draw various types of graphics, you can use fancy complicated animations, but in the end the entire goal is that those fancy graphics and animations must come together to make you understand, to deliver insight about your data – and NOT actually make your data harder to read.
Go ahead. Click that top Dataviz Blog menu. Read or skip the short articles, and play around with the visualisations. Hover, or touch the graphics, see the tooltip, try out the various available controls, experience yourself the ability of d3.js to combine graphics and animations to deliver insight. Have some fun with them.
At the end of each articles are the ‘Fullwidth View’ button where you can experience the visualisation with it’s full functionalities. If your using desktop, don’t hesitate to try.
