如何在 ruby 中可视化哈希数据结构？
我有一个哈希对象，其结构类似于：
{:category1 =>
{:subcategory1 =>
[
{:article => "some article", :date => "2010-04-04"},
...
],
:subc2 => [...]
},
:category2 => {...},
...
}
How can I Visualize it as graph in ruby?
是否有一个简单的方法/gem/lib 可以将此哈希转换为 DOT？
I have a hash object, whose structure looks similar to this:

:subc2 => [...]
},
:category2 => {...},
...
}
How can I visualize it as graph in ruby?
Is there a simple method/gem/lib that converts this Hash to DOT?

为什么你想要它是一个图表？您的示例中的数据是一棵树。
您可以使用 Ruby 漂亮的打印方式轻松地在文本中看到树：
如果您想要更清晰的输出：
Why do you want it to be a graph? The data in your example is a tree.
You can see the tree easily in text with Ruby's pretty print:
If you want a little cleaner output:
我相信您可以使用 ruby-graphviz gem 进行此类可视化。
I believe you could use the ruby-graphviz gem for this sort of visualization.
