在提供的文件信息中,可以看出我们讨论的焦点是一本关于D3.js的书籍,即《Manning.D3.js.in.Action.2nd.Edition.2017.11.pdf》。这本书介绍了数据可视化领域中的D3.js库,以及如何利用JavaScript技术进行web开发和数据可视化。接下来,我将从以下几个方面详细解读文件中所包含的知识点。 首先,文件标题和描述提到D3.js对于不同背景的读者意味着不同的东西。对于以下三个不同领域的从业者来说,D3.js具有不同的意义和用途: 1. 传统JavaScript开发者:这部分读者可能将D3视为一个用于绘制图表(更常见)或地图(较少见)的库。他们可能习惯于使用传统的JavaScript进行数据可视化。 2. 传统软件开发人员:这些人可能熟悉如Java这样的语言,D3.js可能是他们转向前端开发或Node.js开发的一个契机。 3. 以统计分析为主的数据分析师:这类人员通常使用R、Python或桌面应用程序进行数据分析,D3.js为他们提供了一种在web前端进行数据可视化的新途径。 其次,这本书的目标是让读者能够在两个新的领域——web开发和数据可视化中获得更深入的了解。作者通过对D3.js库关键原理的深入解释,帮助读者建立基础,无论读者是D3.js的新手还是已经有一定经验,希望进一步提升技能的开发者。 D3.js是一个开源的JavaScript库,它利用Web标准技术(HTML、SVG和CSS)来创建交互式数据可视化。D3.js之所以特别,是因为它允许开发者以非常灵活的方式操作文档,并且不需要依赖于特定的图形框架。了解以下D3.js的关键概念对于掌握这本书的内容至关重要: - 选择器(Selections):D3.js通过使用类似于jQuery的选择器来操作DOM元素,它允许开发者选择、创建和操作DOM节点。 - 数据绑定(Data Binding):D3.js的核心能力之一是将数据与DOM元素绑定,通过这种方式,数据可以用来生成图形元素的大小、位置、颜色等属性。 - 比例尺(Scales):D3.js提供了强大的比例尺功能,可以帮助开发者根据数据范围将数据值映射到视觉上的比例,这对于创建有效的图表至关重要。 - 动画(Transitions):D3.js使得创建流畅和交互式的动画成为可能,它提供了简单的方法来定义动画的起始点和终点。 - 坐标轴(Axes):D3.js提供了便捷的方法来创建图表坐标轴,并且可以轻松自定义它们的样式和格式。 - 地理映射(Geographic Mappings):D3.js也支持地理空间数据,可以用来绘制地图。 本书将涵盖上述以及其他D3.js的高级话题,并且指导读者如何运用这些工具和概念来创建他们所能想象的任何数据可视化。对于有意深入学习D3.js的读者来说,这本书提供了一个从基础知识到高级应用的完整学习路径,无论读者的基础如何。 最后,文件的标签“D3 Javascript”和文件名称“Manning.D3.js.in.Action.2nd.Edition.2017.11.pdf”为我们提供了关于书籍内容的核心信息,即这本书是关于D3.js的实践指南,并且是第二版,更新于2017年11月。这表明该书内容已经过最新版本的D3.js技术更新,适合寻找最新资料的开发者。

I’ve always loved making games. Board games, role-playing games, computer games— I just love abstracting things into rules, numbers, and categories. As a natural conse- quence, I’ve always loved data visualization. Damage represented as a bar, spells repre- sented with icons, territory broken down into hexes, treasure charted out in a variety of ways. But it wasn’t until I started working with maps in grad school that I became aware of the immeasurable time and energy people have invested in understanding how to best represent data. I started learning D3 after having worked with databases, map data, and network data in a number of different desktop packages, and also coding in Flash. So I was nat- urally excited when I was introduced to D3 , a JavaScript library that deals not only with information visualization generally, but also with the very specific domains of geospa- tial data and network data. The fact that it lives in the DOM and follows web standards was a bonus, especially because I’d been working with Flash, which wasn’t known for that kind of thing. Since then, I’ve used D3 for everything, including the creation of UI elements that you’d normally associate with jQuery. When I was approached by Manning to write this book, I thought it would be the perfect opportunity for me to look deeply at D3 and make sure I knew how every little piece of the library worked, while writing a book that didn’t just introduce D3 but really dived into the different pieces of the library that I found so exciting, like mapping and networks, and tied them together. As a result, the book ended up being much longer than I expected and covers everything from the basics of generating lines and areas to using most of the layouts that come to mind when you think of data visualization. It also devotes some space to maps, networks, mobile, and optimization. In the end, I tried to give readers a broad approach to data visualization tools, whether that means maps or networks or pie charts.
