    Study Notes

    Book Overview

    • The book is divided into three parts: "From Data to Visualization", "Principles of Figure Design", and an annotated bibliography.
    • The book covers static visualizations presented in print, online, or as slides, but not interactive visuals or movies.

    Part I: From Data to Visualization

    • The first part describes different types of plots and charts, with an emphasis on the science of visualization.
    • The part is organized by the type of message the visualization conveys, rather than the type of data being visualized.
    • Topics covered include visualizing data, coordinate systems and axes, and color scales.

    Part II: Principles of Figure Design

    • The second part discusses design issues that arise when assembling data visualizations, with an emphasis on the aesthetic aspect of data visualization.
    • Topics covered include ugly, bad, and wrong figures, and introduction to principles of figure design.

    Part III: Annotated Bibliography

    • The annotated bibliography at the end of the book provides pointers to texts covering visualization software and programming libraries.

    Visualization Topics

    • Visualizing trends: smoothing, showing trends with a defined functional form, detrending, and time-series decomposition.
    • Visualizing geospatial data: projections, layers, choropleth mapping, and cartograms.
    • Visualizing uncertainty: framing probabilities as frequencies, visualizing the uncertainty of point estimates, curve fits, and hypothetical outcome plots.
