My flat timeline doesn't render

[sangwon9029]

Thank you for this great plugin.
The horizontal timeline doesn't show anything, while my vertical timeline works great.
I've added "type=flat" but it doesn't show anything.
Please help me out!

type=flat only applies to the codeblock which you have done correctly.

The issue here is your data-type=flat

data-type can be any of the following values: box (default), point, background, and range.

• background and range require a start and end date.
