Chris Alen Sula (Pratt Institute) has written a post that provides a workflow for creating Lexis Maps in Tableau Public. Recognizing that Lexis maps have application beyond demography, Sula provides readers with step by step instructions for working in Tableau as well as tips and tricks for data preparation.
Though few have heard of them outside of demography, Lexis maps can handle the complex type of data that visualization was meant for: quantitative, longitudinal, high-density, multivariate data. Most Lexis diagrams span a hundred years or more for ages 0–100+, resulting in tens of thousands of data points in a single display.
