Plot x-axis chopped.

[gganapat]

Hi all:

I just tried out lightweight-charts for the first time, and the example plot from Getting Started renders with bottom axis chopped off. I'm doing this in Observable Framework, but I don't think that shoud be an issue.

Any idea on how to fix it? Modifying the bottom margin in <div id='container' style="width: 600px; height: 400px; margin-bottom: 25px;"></div> doesn't seem to help.

Thanks!
