Tree Map Example Trend Chart | Visualization Analysis and Design

Data visualization infographic titled "Tree Map Example" using a TREND LINE (over time) as the dominant visual element to show the breakdown. Create a large central time-series chart with 5 stacked trend lines or clearly separated trend lines representing category breakdown over time, with sharp axis labels and tick marks in English. X-axis label: "Year" with ticks "2019", "2020", "2021", "2022", "2023", "2024". Y-axis label: "Share of Total (%)" with ticks from 0 to 100 at regular intervals, no misleading axis truncation or scale manipulation. Use realistic illustrative values for category breakdown: "Category A" 28, 30, 27, 32, 35, 34; "Category B" 22, 21, 24, 23, 20, 19; "Category C" 18, 17, 19, 18, 17, 16; "Category D" 16, 18, 15, 14, 13, 15; "Category E" 16, 14, 15, 13, 15, 16. Include a clean legend in English: "Category A", "Category B", "Category C", "Category D", "Category E". Add 4 key insight callouts around the chart, each with a headline number, a short interpretation in English, and a small icon: "35%" + "Category A reaches the highest share by 2023" + upward arrow icon; "19%" + "Category B trends downward over the period" + decline icon; "16%" + "Category C remains relatively stable" + balance icon; "100%" + "All categories together show the full breakdown each year" + grid icon. Add a small side panel or footer mini-breakdown table labeled "Illustrative category mix" with percentages by year to reinforce the breakdown storytelling angle. Add a small source / data-note strip in English at the bottom: "Data note: Illustrative example. Figures are illustrative and not sourced from an external dataset." Visual style: retro 1970s magazine charts, editorial blue & cream palette, muted navy, faded cobalt, warm cream background, soft ink texture, subtle halftone print feel, geometric icons, thin vintage rule lines, bold serif title paired with clean sans-serif labels, nostalgic but highly legible. Mood: analytical, stylish, editorial, approachable. Include 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.
