Automotive stocks analysis

The hedge fund has asked you to produce a scatter plot to help them understand the financial performance of two automotive companies: Ford and General Motors.

You will build a plot displaying the close price for each day against the market cap (price multiplied by volume) for the two companies. The fund would like to be able to customize the x-axis, giving you a great chance to implement RangeSlider.
