Data miners work fast. One way to improve your productivity is to take full advantage of tools that let you do several things at once. It’s time-consuming (and boring) to set up a number of graphs separately, one at a time. So use these alternatives whenever you can:
Data summaries
![Data summaries](https://www.dummies.com/wp-content/uploads/446200.image0.jpg)
Tools that let you quickly ask for summaries of many variables, and get the summaries all at once. Bar charts and histograms are often included in the output.
Chart matrix
![Chart matrix](https://www.dummies.com/wp-content/uploads/446201.image1.jpg)
The output is a grid (matrix) of small bar charts and histograms, so you can review many data distributions quickly.
Scatterplot matrix
![Scatterplot matrix](https://www.dummies.com/wp-content/uploads/446202.image2.jpg)
A grid of small scatterplots. Each small graph shows the relationship for a single pair of variables (usually uses continuous variables). You input a list of variables, and the scatterplot matrix shows you every possible pairing.
