Experimenting in Tableau

I spent the past couple of days playing in Tableau.

• I learned how to add labels and marks to just the beginning and ending values, as well as change how those numbers appear.

• I learned how to edit the colors and fonts of the sheets and dashboards.

• I learned how to change the size of the dashboard.

• I learned that I've forgotten some things...

• I figured out how to make a pie chart with percentages!I also learned that the labels can be a bit tricky, but that's more than I knew before!

As far as the Viz challenge goes, I feel like I just don't know what else to do. Like I'm missing something. I check out the submissions online that look so professional and put together, and I have a couple of line graphs and one strangely large bubble chart?

I'm sharing what I have below. Please know that this is definitely not my end product, but it's where I'm at right now.
