Visualizing Data (Paperback)

Description 

Enormous quantities of data go unused or underused today, simply because people can't visualize the quantities and relationships in it. Using a downloadable programming environment developed by the author, Visualizing Data demonstrates methods for representing data accurately on the Web and elsewhere, complete with user interaction, animation, and more.

How do the 3.1 billion A, C, G and T letters of the human genome compare to those of a chimp or a mouse? What do the paths that millions of visitors take through a web site look like? With Visualizing Data, you learn how to answer complex questions like these with thoroughly interactive displays. We're not talking about cookie-cutter charts and graphs. This book teaches you how to design entire interfaces around large, complex data sets with the help of a powerful new design and prototyping tool called "Processing".

Used by many researchers and companies to convey specific data in a clear and understandable manner, the Processing beta is available free. With this tool and Visualizing Data as a guide, you'll learn basic visualization principles, how to choose the right kind of display for your purposes, and how to provide interactive features that will bring users to your site over and over. This book teaches you:

• The seven stages of visualizing data -- acquire, parse, filter, mine, represent, refine, and interact
• How all data problems begin with a question and end with a narrative construct that provides a clear answer without extraneous details
• Several example projects with the code to make them work
• Positive and negative points of each representation discussed. The focus is on customization so that each one best suits what you want to convey about your data set

The book does not provide ready-made "visualizations" that can be plugged into any data set. Instead, with chapters divided by types of data rather than types of display, you'll learn how each visualization conveys the unique properties of the data it represents -- why the data was collected, what's interesting about it, and what stories it can tell. Visualizing Data teaches you how to answer questions, not simply display information.

 

 

描述

大量的數據今天被浪費或未充分利用，僅僅因為人們無法對其中的數量和關係進行可視化。使用作者開發的可下載編程環境，《Visualizing Data》演示了在Web和其他地方準確表示數據的方法，包括用戶互動、動畫等。

人類基因組的31億個A、C、G和T字母與黑猩猩或老鼠的字母相比如何？數百萬訪問者在網站上的路徑是什麼樣的？通過《Visualizing Data》，您將學習如何用完全互動的顯示方式回答這些複雜的問題。我們不是在談論模板化的圖表和圖形。本書教您如何使用一個名為“Processing”的強大的新設計和原型工具來設計整個界面，以處理大型、複雜的數據集。

Processing beta被許多研究人員和公司用於以清晰易懂的方式傳達特定數據，該工具可免費使用。通過這個工具和《Visualizing Data》作為指南，您將學習基本的可視化原則，如何選擇適合您目的的顯示方式，以及如何提供互動功能，使用戶一次又一次地訪問您的網站。本書教您：

- 可視化數據的七個階段：獲取、解析、過濾、挖掘、表示、精煉和互動
- 如何使用Processing進行數據可視化
- 如何設計互動界面
- 如何選擇適合的顯示方式
- 如何提供互動功能

《Visualizing Data》是一本教您如何將數據可視化的實用指南，幫助您更好地理解和呈現數據。
