Programming Languages Popularity Ring Chart

A square data-visualization tile showing a multi-layer ring chart of programming language popularity for a fictional 2025 developer survey. Dark graphite background, faint dot grid. The chart has two concentric rings. The outer ring is divided into ten color-coded segments labelled with language names and percentage: "JavaScript 28%", "Python 24%", "TypeScript 14%", "Java 9%", "C# 6%", "Go 5%", "Rust 5%", "Kotlin 4%", "Swift 3%", "Other 2%". The inner ring groups them by paradigm with thinner labels: "Web", "Data and ML", "Systems", "Mobile". A clean key at the top-right lists each language with a color swatch and a tiny trend arrow (up, down, flat). The headline above the rings reads "Languages Devs Actually Used, 2025". Below the rings, a single line of source attribution reads "Source: fictional survey, n = 12 480". Typeface is a precise geometric sans-serif, all percentages aligned in tabular figures, color palette built from cyan, magenta, lime, amber, violet against the dark base, two-pixel separators between ring segments.
