商品描述

An accessible primer on how to create effective graphics from data

This book provides students and researchers a hands-on introduction to the principles and practice of data visualization. It explains what makes some graphs succeed while others fail, how to make high-quality figures from data using powerful and reproducible methods, and how to think about data visualization in an honest and effective way.

Data Visualization builds the reader’s expertise in ggplot2, a versatile visualization library for the R programming language. Through a series of worked examples, this accessible primer then demonstrates how to create plots piece by piece, beginning with summaries of single variables and moving on to more complex graphics. Topics include plotting continuous and categorical variables; layering information on graphics; producing effective “small multiple” plots; grouping, summarizing, and transforming data for plotting; creating maps; working with the output of statistical models; and refining plots to make them more comprehensible.

Effective graphics are essential to communicating ideas and a great way to better understand data. This book provides the practical skills students and practitioners need to visualize quantitative data and get the most out of their research findings.

  • Provides hands-on instruction using R and ggplot2
  • Shows how the “tidyverse” of data analysis tools makes working with R easier and more consistent
  • Includes a library of data sets, code, and functions

 

商品描述(中文翻譯)

這本書是一本關於如何從數據創建有效圖形的入門指南。它為學生和研究人員提供了一個實踐數據可視化原則的實踐機會。它解釋了為什麼有些圖表成功而其他圖表失敗,如何使用強大且可重複的方法從數據中創建高質量的圖形,以及如何以誠實和有效的方式思考數據可視化。

《數據可視化》通過一系列的實例演示了如何逐步創建圖形,從單變量的摘要開始,進而涉及更複雜的圖形。主題包括繪製連續和分類變量;在圖形上添加信息;生成有效的“小多個”圖形;對數據進行分組、摘要和轉換以進行繪圖;創建地圖;處理統計模型的輸出;以及改進圖形以使其更易理解。

有效的圖形對於傳達思想和更好地理解數據至關重要。這本書提供了學生和從業人員在可視化定量數據方面所需的實踐技能,以充分利用他們的研究成果。

本書提供了使用R和ggplot2進行實踐指導,展示了數據分析工具“整潔宇宙”的使用如何使R的操作更加容易和一致。書中還包含了一個數據集、代碼和函數庫。
