I have linked the BOM Perth Weather Forecast website.
It is a familiar and simple example of presenting raw data in a meaningful, informative way. Weather forecasters take data like temperature, wind speed, atmospheric air pressure, wind direction, humidity and other indicators and translate them into the weather for the near future. Individually, the data sets mentioned above are meaningless to many people- but when a qualified person considers them together, the information provided impacts our lives daily.
