Scatter Plot Trendline Sankey for Data Studio Community Visualizations

Data visualization infographic titled "Scatter Plot Trendline" featuring a SANKEY FLOW as the dominant visual element, adapted as a pipeline-style analytical infographic that visually explains how scattered observations consolidate into an overall upward trend. Main composition: a large central hybrid chart where neon data points are distributed across a dark Cartesian plotting area with sharp English axis labels and clear tick marks, while flowing sankey-style bands connect low-value clusters on the left to mid-value clusters and then high-value clusters on the right, emphasizing trend progression. Include a bright linear trend line running diagonally upward across the scatter field. X-axis label exactly: "Input Variable" with ticks "0", "10", "20", "30", "40", "50". Y-axis label exactly: "Observed Output" with ticks "0", "20", "40", "60", "80", "100". Cluster labels in English: "Low range", "Mid range", "High range". Flow labels in English: "Emerging pattern", "Concentration", "Strong upward trend". Use realistic plausible illustrative values such as 18 points in low range, 27 points in mid range, 21 points in high range, with trendline equation label "Trend line: y = 1.6x + 12" and correlation note "Illustrative r = 0.78". Add 4 key insight callouts around the chart, each with a headline number, short interpretation in English, and a small icon: 1) "0.78" + "Strong positive correlation in this illustrative sample" + upward arrow icon; 2) "66%" + "Most observations concentrate in mid-to-high values" + cluster icon; 3) "+52" + "Output rises by roughly 52 units across the full input range" + line-chart icon; 4) "3 stages" + "Pipeline view highlights how scattered data resolve into a clear trend" + flow icon. Add a small bottom strip in English with exact text: "Data note: Illustrative example. Figures shown are not sourced and are for visualization purposes only." and "Scale starts at zero; no axis truncation." Visual style: Reuters / Economist editorial, dark mode neon palette, charcoal-black background, electric cyan, magenta, lime, and amber accents, restrained newsroom typography, subtle gridlines, high contrast, analytical and credible mood. Include concise legend in English: "Data points", "Trend line", "Flow intensity". Ensure clean spacing, sharp labels, precise ticks, balanced annotation hierarchy, editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no fake authoritative sources cited, no watermarks Numbers labeled "illustrative" unless the user supplied specific sourced data. No fake authoritative sources cited (do not invent "Source: Reuters 2025" — use "Illustrative example" instead). No misleading axis truncation or scale manipulation.
