Is there any method I could use to render no data placeholder

is there any method I could use to render no data placeholder, just like screenshot below?

Hello Kevin,
There is no built-in feature to do that. But you can implement it by using Gantt API and Javascript. Here is an example:

That helps, thanks Ramil ~~~

Hello Kevin,
The dev team added the feature that allows showing the empty state screen:

You can see how it works in the following sample:
