直径+1。 它也是跨平台的，这赢得了我的青睐。 Dia 的另一个优点是图表存储在压缩的 XML 中。
我有一个项目，需要在数据库中绘制一些图表，并且我能够编写一个程序来从数据库创建与 Dia 兼容的 XML，这节省了我大量的打字和绘图工作。 我只需要重新定位对象并调整其大小。
+1 for Dia. It's also cross-platform, which won me over. Another advantage of Dia is that the diagrams are stored in compressed XML.
I had a project where I needed to diagram something in the database, and I was able to write a program to create Dia-compatible XML from the database, which saved me a HELL of a lot of typing and drawing. I just had to reposition and resize the objects.
