13個JavaScript圖表（JS圖表）圖形繪製插件【轉】

如今網絡上又有愈來愈多的免費的（JS 圖表）JavaScript圖表圖形繪製插件。我以前給一家網站作過複雜的圖形，咱們用的是 highchart。在那段時間，沒有不少可供選擇的插件。但如今不一樣了，很容易就能夠找到不少功能很是不錯的圖表庫。我的而言，此類插件的上升，是由於：

1. Flash 過去是最佳解決方案，但不少人多在從那遷移；

2. 現代瀏覽器及其更強大的計算能力，使其在轉化繪製實時數據方面的能力更佳；

3. 繪製矢量圖的不一樣技術愈發成熟：VML、SVG 和 Canvas。

固然了，你須要仔細選擇，以符合自身需求。正如前面提到的，正因使用了各類技術，所以一些支持Canvas的插件僅須要一個現代瀏覽器。

在這篇文章中，咱們已收集 13 個JavaScript圖表和圖形繪製插件。少數是獨立的框架，大多數支持條圖、線圖、餅圖等基本圖形，不少甚至支持更加複雜的圖形，好比：維恩圖、熱圖、進化樹、二維散點圖、二維散點氣泡圖、三維散點圖等。相信你應當能在這個列表中找到所需的。
