  1. Chameleon Graphing: The Coordinate Plane - Ursula Whitcher
    A Web unit that introduces the coordinate plane, for elementary and middle school students. With the help of Sam the Chameleon, learn to find points on a number line and graph points in the coordinate plane. See also Whitcher's companion units on Lines and Slope and Plane History. more>>

  2. ClarisWorks Graphing: Spreadsheet Lessons - Suzanne Alejandre
    Step-by-step directions for using ClarisWorks spreadsheets, helpful in exploring the differences between exponential functions and linear functions. Bar graphs, pie charts, pictograms, and other graphs for linear, polynomial, and exponential functions. more>>

  3. Create a Graph - National Center for Education Statistics (NCES)
    Create your own graphs online: bar graphs, line graphs, area graphs, pie charts, or XY graphs (line, bubble, or scatter plots from Cartesian coordinates). Enter your own data, choose your own labels, preview your work, then print or save your graphs. With examples. From the NCES Students' Classroom. more>>

  4. Edward Tufte
    The work of Tufte and Graphics Press. Read testimonials about his books and purchase them online: The Graphic Display of Quantitative Information, Envisioning Information, and Visual Explanations: Images and Quantities, Evidence and Narrative. In the Ask E.T. moderated forum, Tufte answers questions dealing with information design. Register for his one-day course, "Presenting Data and Information," which covers fundamental strategies of information design; evaluating evidence used in presentations; tables, graphics, semi-graphics, and other statistical data; complexity and clarity; use of video, overheads, computers, and handouts; multi-media, internet, and websites. The section titled "New ET Writings, Artworks, and News" includes Graphics of the Day, "Long-term survival rates of cancer patients achieved by the end of the 20th century," translations of Charles Joseph Minard, and classic articles, such as Stephen J. Gould's "The Median Isn't the Message," Frederick Mosteller's "Classroom and Platform Performance," John W. Tukey's "Some Graphic and Semigraphic Displays," and Austin Bradford Hill's "The Environment and Disease: Association or Causation?" Preview and buy ghost grid printed on acid-free paper "for artists and scientists," and posters of Tufte's own "The Cognitive Style of PowerPoint"; Russian cosmonaut, Georgi Grechko's "Historic Visual Diary of Spaceflight: Cyclogram"; and "Napoleon's March," Minard's portrayal of the losses suffered by Napoleon's army in the Russian campaign of 1812. See also Tufte's fine art and sculpture, including Escaping Flatland and "Cognitive Art: A Portfolio of Five Original Prints," from Envisioning Information. more>>

  5. Gallery of Data Visualization - Michael Friendly, York University
    Examples of the best and worst of statistical graphics, from what is arguably the best statistical graphic ever drawn, to the current record-holder for the worst. more>>

  6. The Man Who Makes Sense of Numbers - Michael H. Martin, Fortune Magazine
    A Fortune article describing the work of Yale professor Edward Tufte, author of the book The Visual Display of Quantitative Information, whose mission is to improve the way we visually present data and information. more>>

  7. Math and the Media: Deconstructing Graphs and Numbers - Jeff Goodman
    Sample graphs and questions about them, focusing on the information the graph is purported to convey and the manner in which it does so. Topics include examples of raw data, misleading graphs, and graphs as advertising. more>>
