Super Leanpub Extrapolation
A multi-line chart tracks the daily sales ranks of nine Leanpub books over several months, plotting cumulative book counts on the y-axis against time on the x-axis. Distinct stroke colors differentiate each book, revealing relative popularity trends, including one book’s rapid rise. The visualization uses D3.js (v3) with `d3.svg.line` and basis interpolation to smooth paths, paired with `d3.time.scale` for the date axis. Data comes from a CSV file of daily snapshots, rendered as SVG with axis and gridline styling via CSS.
