Programming

You are provided with a csv file that contains sales (in CAD) of cars, bikes, and trucks for every month in the year 2016.

You are required to Implement an interactive stacked bar chart, similar to the dancing histograms by Dix and Eliis on the page: http://www.meandeviation.com/dancing-histograms/. The data is about automobile sales. The x-axis should represent the month and the y-axis should represent the sales. When the user clicks on a category, the visualization should update such that the bars of the selected category align. Your visualization should have following features:

1. Interaction (3) : Selecting a category either in the legend or in the bars should result in alignment of the bars of the selected category.
2. Legend (1) : Create an interactive legend which shows the different categories and allows the user to align bars by clicking on a category in the legend
3. Axes (0.5): The x and y axes should be created, and labelled appropriately.
4. Labeling (0.5) : Each bar of each variable must have its numeric value shown as text.

Advice

Advice

Labeling large values such as 100,000 can clutter your visualization. Try using symbols such as K for 1000, Thus 100,000 can displayed as 100K.

Data

A little automobile sales dataset: AutomobileSales.csv
