Project Description
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: Diamond prices.xlsx Download Diamond prices.xlsx. 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, let’s 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 https://www.diamonds.pro/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.
