Visualizing a Million Time Series with the Density Line Chart (arxiv.org)
Data analysts often need to work with multiple series of data---conventionally shown as line charts---at once. Few visual representations allow analysts to view many lines simultaneously without becoming overwhelming or cluttered. In this paper, we introduce the DenseLines technique to calculate a discrete density representation of time series.

What Killed Innovation? (shirleywu.studio)
I entered the data visualization field in 2012, when D3.js had just come out and interactive graphics were going through a digital Renaissance. By the time I was fully steeped in the field in 2016, it felt like a new, experimental project was coming out every week—each one pushing the boundaries of how we think about, visualize, and communicate data.
