You will be asked to sketch a data series visualization using either a pen (then scan or photo the results) or any software for drawing on your computer. You may also use any other tool to draw the chart (e.g. Excel, Tableau), but it is not required.

The attached files provide you data of a daily use of Chicago bike sharing system (Divvy) for October-December 2017. This dataset also includes some weather information for the same period.

Make a preliminary analysis of the relation between weather data and the number of rides. Select at least one weather variable that has the strong effect on the number of rides.

Choose an appropriate type of visualization. Sketch a visualization of the use of the bike sharing systems over time explaining at least two reasons for the number's fluctuation from day to day.

The sketch does not have to show all data points, but it has to give an idea of the causes of fluctuations.

Provide commentary explaining what effects and how did you illustrate with your sketch.
