內容簡介

D3 是目前流行的數據可視化工具。它是一個基於數據操作文檔的JavaScript 函式館，因為其優雅靈活的語言風格，生動有趣的互動功能，花哨酷炫的表現力，受到越來越多的人關注和喜愛。

《D3 API詳解（全彩）》基於官方API 文檔，在儘量保留原文含義的基礎上，對部分內容進行了刪減和增補，幾乎為每個函式都添加了淺顯直觀的案例。《D3 API詳解（全彩）》涵蓋了API 大部分內容，包括核心函式中的選擇器、過渡、數組、數學、數據請求、格式化、本地化；3 類9 種比例尺；D3 對SVG 繪圖技術的封裝，如SVG 元素、多種路徑生成器、數軸、刷子等；時間函式；12 種布局，如捆、弦、樹、簇、包、分區、矩形樹、力、直方圖、堆疊等；地理函式，如投影、流、地理路徑、經緯網等；還有幾何圖形，像四叉樹、凸包、多邊形、泰森多邊形等；以及互動行為中的拖動和縮放。

《D3 API詳解（全彩）》適合所有想使用D3 實現數據可視化方案的人使用。讀者朋友可以將《D3 API詳解（全彩）》作為入門參考，也可以作為速查手冊。
