An excellent tool is Weka. It accepts data in csv as well as arff format. It is free and open source, can be used to visualize as well as to run inbuilt machine learning algorithms to gain more insights into the data. The best thing is that it is extremely light weight and easy to use, you don't need anything except support for java.
IBM's Many Eyes project is a free web-based collaborative tool that has lots of charts available.
Better, but expensive, are Spotfire and Tableau. Both are amazing commercial applications for this, and Spotfire especially is incredibly easy to use to explore lots of visualizations side-by-side. Both have a desktop version and an online web player (Spotfire demo gallery, Tableau demo gallery). They are both highly scalable, into the millions of rows. Both have free trials.

一个优秀的工具是 Weka。它接受 csv 和 arff 格式的数据。它是免费且开源的，可用于可视化以及运行内置的机器学习算法，以获得对数据的更多见解。
最好的事情是它非常轻量且易于使用，除了支持
java之外，您不需要任何东西。从此处获取它。一旦开始，它看起来像：
现在转到资源管理器，打开文件，就完成了！

Now go to Explorer, open file and you are done!
IBM 的 Many Eyes 项目是一个免费的基于 Web 的协作工具，它具有有很多可用的图表。
更好，但价格昂贵的是 Spotfire 和 画面。两者都是令人惊叹的商业应用程序，尤其是 Spotfire 非常易于使用，可以并排探索大量可视化。两者都有桌面版本和在线网络播放器（Spotfire 演示库、Tableau 演示库）。它们都具有高度可扩展性，可扩展至数百万行。两者都有免费试用。
