A17 – Scales

The purpose of this assignment is to practice using D3’s scaling functions.


For this assignment create files named scales.html, scales.css, and scales.js.

Find some time series data on the Internet that includes at least 3 dimensions of data.  One dimension must contain at least 20 data points and another dimension must contain dates. Your data should not be the same data you used in a previous assignment or the same data used by other students in the class.

When your page loads, your scales.js file should create a plot where each of your data elements is represented by a circle and one of the axis represents time.  How you represent the other dimensions is up to you.

You may have a placeholder svg element in scales.html, but the svg element should not have any child elements.   Please title your plot and provide a proper citation for the data source including a link.
