Data visualization is represented here by showing current and forecast weather charts for the New York City area. Current weather data is retrieved from an XML file using the simplexml_load_file PHP function. Forecast data is parsed from a raw text file using the file_get_contents function. Each function calls live weather data provided by NOAA and updates once an hour. Occasionaly during overnight hours some data points may not be available.
A user can mouse over (or tap) on any individual element of the charts to get more detailed information. This allows a large amount of data to be visualized in a small screen area.
