An histogram is an accurate graphical representation of the distribution of numeric data. It takes as input one numerical variable only. The variable is cut into several bins, and the
number of observation per bin is represented by the height of the bar. Note that the shape of the histogram can be really different following the number of bins you set. Thus, try different
values before taking any conclusion. Note that it is really close to density plot. To compare several distributions, add them on the same axis or use violinplots.
The ggplot2 library offers a specific function to draw histograms: geom_histogram. Here are a few examples:
Of course the base version of R can handle very well the creation of histograms as well:
Contrary to other chart type (like scatterplot), interactivity does not improve much your histogram. Still, here are a few examples of interactive histograms using the plotly library. If you have a low number of observation, you can consider doing an interactive dotplot histogram as proposed below.
