Documentation problem

When value_name is an existing column name, a ValueError is raised. The args documentation doesn't mention this.

Suggested fix for documentation

Update the value_name documentation from:

value_name: scalar, default ‘value’
Name to use for the ‘value’ column.

to something like

value_name: scalar, default ‘value’
Name to use for the ‘value’ column. Can't be an existing column name

Hello, I took this task because I am new in the open source community, therefore I thought that would be good to get a simple one, but I am not being able to find the doc to update, could you help me to find it? But only if you already know where to look.

@thiagogquinto a search of Name to use for the ‘value’ column. in the repository will point you to these lines.
