Weather Depiction Charts are a visual representation of METARS and MVFR.

Weather Depiction Charts are a map-style summary of aviation weather that uses surface observations to show how the sky and visibility look across a region. The key data source behind these charts is METARs, which report current ceilings and visibility. Those numbers are then translated into flight categories, including MVFR, and the chart shades or symbols areas accordingly. So the chart visually communicates MVFR conditions where the METAR data place those ceilings and visibilities in the MVFR range, while also showing other categories as needed. Because it relies on METAR observations and explicitly displays MVFR conditions, it best fits as a visual representation of METARS and MVFR. For context, MVFR means ceilings roughly between 1,000 and 3,000 feet and/or visibility between 3 and 5 miles, which is exactly the range shown on the chart when those conditions are present.
