开发网络可视化应用，一般还是选择基于这几类语言的可视化框架。
虽然C++和Java语言的框架能够通过Applet，或者上层封装Actionscript或Webgl的形式实现网络应用，但是一般会有使用与网络传输，效率问题等。
下面按照一定的文档格式介绍不同的框架。
一，C++：
VTK（VisualizationToolkit）；
1，VTK
官网：
http:
//www.vtk.org/
介绍：
一个开放资源的免费软件系统，跨平台、支持并行处理，主要用于三维计算机图形学、图像处理和可视化。
Vtk是在面向对象原理的基础上设计和实现的，它的内核是用C++构建的，包含有大约250,000行代码，650多个类，还包含有几个转换界面，因此也可以自由的通过Java，Tcl/Tk和Python各种语言使用vtk。
Vtk几乎可以在任何一个基于Unix的平台上操作，以及Windows95/98/NT/2000/XP/7。
语言环境：
C++,JavaApplet,VRML;
主要特征：
a, 具有强大的三维图形功能。
支持体绘制，面绘制，多种Shader；
充分利用现有的图形库和图形硬件。
b,优良的流streaming和高速缓存caching的能力，处理大量数据时不必考虑内存资源的限制。
c,支持网络应用，比如JavaApplet和VRML。
d,跨平台，设备无关性，可移植性
应用：
VTK是一个开放源码、自由获取的软件系统，全世界的数以千计的研究人员和开发人员用它来进行3D计算机图形，图像处理，可视化。
通过对体、面、光源等的逼真渲染，VTK应用于核医学成像等科学可视化领域。
二，Java：

●支持由表，图，树组成的数据结构，字段的数据索引和选择列的查询，并且高效的利用内存；
●动态查询过滤数据显示；
●融合使用了lucene文本查询engines；
●在位置和动画中利用了物理学中力的摸拟；
●内建类似于SQL的语言语句可以针对数据进行行和列的操作；
●支持数据库的查询结果集合和prefuse内部数据的映射；
●可以利用经过简化的，对开发者友好的API，建立自定义的过程，用户交互和画图像的组件。
（貌似提供了很强的数据查询和处理的功能？

创建表格，如条形图、线条图、饼图、时间序列表、烛台图表、高/底/开/闭表、风向图、和仪表。
我希望这些表格看上去更棒，因为其功能和特点都很出色，但是视觉设计真的有点“贬损”这些图形。
JFreeChart朋友们，给我发送邮件吧，我们可以把JFreeChart世界变成一个更美的空间。
