Today I learned that Google Sheets has a sparkline feature called "=SPARKLINE". The name is apt. This feature lets you create a trend line of data points over time. I saw this in use in a Google Sheet and loved it. My first thought was "it must have taken a lot of work to make those lines." Then I found out those lines were created with a built-in Sheets function. Isn't that cool? I thought back to all of the time I spent building sparklines for my blog, visible on my home page and category pages, to show trend lines in my publishing. I spent hours thinking through sparklines.
