Analyzing top customer locations

From your good work with the e-commerce company, you have been asked to help them build on an existing report looking at their sales by country.

The sales manager is interested in understanding where their top customers are located. They don't currently have a clear idea of what 'top' means. Ideally, they can easily try a variety of different cut-off values to consider someone a top customer and see how the graph changes with different cut-off values.

Your task is to help the sales manager by using a range input to facilitate a live-update app that filters sales by a minimum OrderValue amount.

Create an input that the user can slide to select a value between 50 and 550 below line 46.
Ensure the callback is triggered whenever the slider stops moving below line 49.
In the triggered callback, check if an input has been entered below line 78 and, if so, use the input to filter for sales with an OrderValue strictly greater than the input.
In the plot, insert the user input value into the title, so users know what has been selected below line 85.
