ScatterRViz

ScatterRViz is a custom visual for showing three variables in one chart. There is a possibility to zoom in and zoom out on the chart.

This custom visual needs

1-      X-axis as the first variable

2-      Y-axis as the second  variable

3-      Color (categorize variable) for the third axis

To use this chart, you need:

1-      One R version in your machine

2-      Automatically, some of the packages like “plotly,” “ggplot2”, and “htmlwidgets” will be installed.

3-      If these packages did not install automatically, then we need to install them in Rstudio via below commands:

Install.packages(“plotly”)

Install.packages(“ggplot2”)

Install.packages(“htmlwidgets”)

In below example, I have shown the speed in the city and highway with a number of the cylinder as color. The speed in the city has been shown in the x-axis, speed in the highway has been shown on the Y-axis and the number of cylinders will be shown as different color.
