This document shows an example of making a web presentation with graphics, using R Markdown (http://rmarkdown.rstudio.com), Slidy and Plotly (https://plot.ly/) together, corresponding to the assignment of Week 3 of the Developing Data Products course from Coursera (https://www.coursera.org/learn/data-products).

Data used by the example is the Iris Data Set. This dataset contains 3 classes of 50 instances each, where each class refers to a type of iris plant.

This presentation will show a scatter plot where the X-Axis is the column Sepal.Length, the Y-Axis is the column Sepal.Width, and the dots’ colors are based on the column Petal.Length.
