The importance of visualizing data
As one of our leading examples (thank you, Alberto Cairo) once stated, any chart, no matter how brilliantly made, will lead us astray if we don’t pay attention to it!
It has never been more vital than now to be able to interpret graphs, tables, and infographics as we have all learned how to deal with data and produce fascinating and wonderful representations for our viewers. However, if it is poorly built and we are unable to recognize defects in the graphs, we may make incorrect conclusions.
Going back in time, we began many years ago by making visualizations. Hundreds of drawings of our forefathers might be found in the Altamira caves in Spain. And it’s difficult to believe that these drawings are around 15,000 years old, making them the oldest in the world. Figure 7.1 depicts one of Altamira’s incredible cave artworks:
