I need to plot a bar chart where the values is a price range.
In my graph the x-axis is a price range (i.e. 25, 50,100, etc) and the
y-axis is the product name (i.e. toyota, honda, bmw, mercedes, ferrari). The
bar should reflect the position of a prodcut name's price range (i.e. toyota,
25-50) in the graph.

This way toyota will have a bar starting from the 25 grid to the 50 grid,
honda (30-60) will have a bar starting from 30 grid to the 60 grid, etc.
