Setting up Danfo.js for plotting
By default, Danfo.js provides some basic chart types. These charts can be called on any DataFrame or Series object and, if the correct arguments are passed, it will display the corresponding chart.

- Line charts
 - Box and violin plots
 - Tables
 - Pie charts
 - Scatter plots
 - Bar charts
 - Histograms
 
These charts are exposed via the plot function. That is, if you have a DataFrame or Series object, calling the plot function on them exposes these charts.

const df = new DataFrame({...})
df.plot("my_div_id").<chart type>
			The chart type can be line, bar, scatter, hist, pie, box, violin, or table.  
Each plot type will accept plot-specific arguments, but...
