It can be used to draw many different kinds of diagrams. It currently has special objects to help draw entity relationship diagrams, UML diagrams, flowcharts, network diagrams, and many other diagrams. It is also possible to add support for new shapes by writing simple XML files, using a subset of SVG to draw the shape.
作为一个额外的好处，GraphViz 作为插件可以与许多 wiki 软件包一起使用...Confluence、MediWiki、Trac，对于初学者来说。
Use GraphViz. At its core, it's a description language that produces decent graphcs automatically. Another answer recommended Dia... Dia is a GUI tool that produces GraphViz .dot files. If you want total layout control (generally not necessary for a flowchart), use Dia. If you just want something that produces a reasonable layout by itself, use GraphViz directly.
As an added bonus, GraphViz works with many wiki packages as a plugin... Confluence, MediWiki, Trac, for starters.
Google Drawings has been released since this question was answered. It has several built-in flowchart stencils, or check out the templates to find some more elaborate flowchart elements that you can copy-paste into your document.
如果您有 Microsoft Word 或 Excel，则可以选择“插入|形状|流程图”来创建流程图。 我知道它不是免费的，但如果您已经有 Microsoft Office，它可能是一个选择。
If you have Microsoft Word or Excel you can select Insert|Shapes|Flowchart to create a Flowchart. I know it is not free but if you have Microsoft Office already, it may be an option.

我使用了draw.io，它非常好。
I used draw.io and it is very good.
使用 GraphViz。 从本质上讲，它是一种可以自动生成良好图形的描述语言。 另一个答案推荐 Dia...Dia 是一个生成 GraphViz .dot 文件的 GUI 工具。 如果您想要完全布局控制（通常流程图不需要），请使用 Dia。 如果您只是想要自己产生合理布局的东西，请直接使用 GraphViz。

自此问题得到解答后，Google 绘图已发布。 它有几个内置的流程图模板，或者查看模板以查找一些更复杂的流程图元素，您可以将它们复制粘贴到文档中。
