This guide is about two things:1. Introduce you to the basic concept of Data Visualisation. Bear in mind this guide is intended for business people whose main concern is how to practically visualise data. So, the explanation will be short, 'punchy', and focusing on the basics of graphs, not in the details of the design.2. Show you how to do Data Visualisation in R, one of the world's most powerful and comprehensive modelling platforms-which is also free of charge (special thanks to all the good people out there). The intention is not to teach you the best practices of data visualisation, but to provide 'quick and dirty' codes for you to start building your data visualisation in less than five minutes.
