Manhattan Plot of Manhattan

This technical blog article details the process of creating a specialized data visualization called a 'Manhattan plot' to display the heights of buildings in Manhattan by their year of construction. The author explains the data source (NYC Open Data), the challenge of plotting ~35,000 buildings, and the specific coding and design techniques used, such as jittering x-values, mapping height to color/opacity, and using thin outlines to manage overplotting and visual density.
