By default, most chart types in Tableau come with axis lines, borders, and reference lines. Bet rid of these, unless you absolutely need them (e.g, horizontal gridlines in a line chart). SEE STEP 1 - LOSE THE LINES.
Oftentimes, your title describes in enough detail what is being shown. So, you usually won't need headers (aka: field labels or axes' titles) that say things like Year, Percentage, or Race/Ethnicity. Here's how to remove field labels. SEE STEP 5 - HIDE FIELD LABELS FOR ROWS.
How to format the colors of a bar, line, or other chart in Tableau. If you want one category to stand out, color all the other categories one color, like grey, then color the category that you'd like to standout in a pop-out color.
This webpage provides instructions for how to sort data, including putting bars in order by size. (Only do this if the categories don't already have an order. Things like years or age groups should stay in order of that category, but things like sex and race/ethnicity can be sorted by size.)

Directly Labeling a Line Chart
To directly label a line chart. Drag the variable that decides the lines to the Label box in the Marks area. For example, if you have a line for male and a line for female, you would drag Sex to the Label Box. If you have different age groups, you would drag Age Group to the Label Box.
Next, click the Label box, and select "Show Mark Labels" and choose "Most Recent." (see right image) You may have to click on the labels and move them on the chart if they are in a weird spot.
Adding a Reference Line (like Total or Average) to Your Chart
Perhaps you have your rates broken up by ethnic group or sex, but you want to also show the overall rate. Don't add another bar to your bar chart for the average or total, add a reference line! See the following PDF with steps.
To embed your chart onto your website, you should drag the box onto your website that will allow you to input custom HTML code. The name for this box differs by website builder. See detailed instructions below.
NOTE FOR WIX WEBSITES: The guided setup (aka: Wix ADI) does not allow for embedding custom code. So, you will need to exit the guided setup and go to "Advanced Editor" when embedding your Tableau charts.
