Data Visualization

Please note: this is an individual assignment.

Assignment Description

This assignment will allow you to apply the principles of data visualization to a real-world dataset.

You will have to create a scatterplot and then interpret your graph.

Dataset: . This dataset contains multiple variables related to diamonds and their characteristics that you can analyze and visualize.

Instructions

Your task is to visualize with a scatterplot a potentially interesting relationship between two variables that is worth visually exploring.

Scatterplot Creation

Using the dataset provided, create a scatterplot that represents the relationship between diamond carats and prices (in USD).

As there is a huge number of registers, lets apply some filtering to plot just the best diamonds included in the dataset. The best diamonds in this dataset have Color D and Clarity VVS1. If you would like to learn more about what these codes mean, as well as the rest of the columns included in the dataset, this webpage provides very clear explanations education/.Links to an external site.

Add Cut to the color mark to add an additional analysis dimension to your chart.

Write a takeaway title that communicates something related to Ideal cut diamonds. What else could you do to provide more detailed information to the users of your chart regarding each one of the represented diamonds?

Your scatterplot should be clear, accurate, and easy to interpret. As part of your submission, you should include the following:

an explanation of your design choices, such as the color scheme you have chosen
a clear and thorough interpretation of what your scatterplot shows about the relationship between the studied variables

Remember, the key to a good scatterplot is not only in its aesthetic appeal but also in its ability to clearly and effectively communicate existing patterns, correlations, or outliers in the data it represents.

Submission

Please submit your scatterplot as a Tableau packaged workbook (.twbx file) and your written interpretation in PDF format.
