A scatter plot is a set of dots plotted on a plane coordinate system representing two variables.
A scatter plot is usually the first choice for data exploration. Simple one-sized data marks give a clear view of every observation’s positioning. A scatter plot is often used to find correlations between two numerical variables and identify patterns. Clusters, as well as outliers, are also easy to spot using scatter plots.
A scatter plot is a chart with one of the best data/space ratios.
A scatter plot is also known for its versatility. It gives a lot of inspiration to infographic designers and data visualization specialists. It can be turned into almost any chart: heatmap, dot plot, icon chart, tilemap, or some hybrid chart.
If you use a combination of numerical and categorical axes and the plots on the numerical axis are dense, you might run into overlapping data marks. To avoid that you can use the Jitter property along the categorical axis. It allows you to spread data marks near the category line and make the data marks more visible.
