Day 6: Telling the story of names.

Coding Methods and Calculation Questions

Let’s review canvas and make sure we understand the checkpoints.

How does your name at your birth year compare to its use historically?

To be truthful and revealing, data graphics must bear on the question at the heart of quantitative thinking: “Compared to what?” The emaciated, data-thin design should always provoke suspicion, for graphics often lie by omission, leaving out data sufficient for comparisons. Edward Tufte

What are some charts types we could use to answer this question?

There is a clear first choice, but I think there are a few other choices that could provide insight.

Use the query() method and filter() method to get your name and years in the rows with and include the name, year, and Total columns

filter the data down to your names (query)
select the pertinent columns (filter())
Create a new data object for your name.

Create a chart with lines and dots to chart the data

base = (alt.Chart()
    .encode(
        alt.X(''),
        alt.Y('')
    )
`"

Create a new DataFrame with your birthday information in the row

Create a DataFrame with x, y, and label as columns. help

Add the vertical rule mark to show your birthday

Add a horizontal line to an existent chart

Work with your partner to create a line chart that includes both of your names?

Can you include total and data for the state in which you were born?
Work together to make the code as eloquent as possible.
compound charts

Can you modify your previous chart to include your birth state?

Can you include Total and your birth state?
Is there a better metric than raw counts that you could calculate?
Are there good labels that you could include on the chart (mark_text())?

Now come up with a different chart than a line chart

Just use your state count our the Total count for your name.
