step exploratory data analysis these plots can be combined to provide even more insightas shown in figure overlaying several plots is common practice in figure we combine simple graphs into pareto diagramor - diagram figure shows another techniquebrushing and linking with brushing and linking you combine and link different graphs and tables (or viewsso changes in one graph are automatically transferred to the other graphs an elaborate example of this can be found in this interactive exploration of data facilitates the discovery of new insights figure shows the average score per country for questions not only does this indicate high correlation between the answersbut it' easy to see that when you select several points on subplotthe points will correspond to similar points on the other graphs in this case the selected points on the left graph correspond to points on the middle and right graphsalthough they correspond better in the middle and right graphs - - - - - - - - figure drawing multiple plots together can help you understand the structure of your data over multiple variables
