This example shows an interactive command-line tool that asks a user for latitude and longitude coordinates, then displays nearby trails on a map. The visualization first captures raw text input, strips spaces, and splits it into latitude and longitude values, which are then passed to a function that queries trail data. While the code itself does not include rendering libraries, it prepares a URL query string with `lat` and `lon` parameters for a web-based map request. The example highlights a straightforward data-flow pattern: user input is parsed and forwarded to a data-fetching routine, with no explicit charting or mapping library used in the visible snippet.
