Prepopulate Date Range when the app loads for the first time

Suggestion

Prepopulate the Date Range when first loading the app in the browser.
This suggestion comes from here.

Rationale

Some first-time users might think that the app looks broken when they see empty spaces where the charts and graphs would be displayed.

On the query page I would only use a range of a day or so. Not great to send the user potentially a lot of data which they might not care about.

On the statistics page it can be the current month or so.
