sankeyflowshow Line Chart Best Practices Infographic

Data visualization infographic titled "Line Chart Best Practices" using a COMPARISON COLUMNS framework adapted into a dominant small-multiples grid of mini line charts that shows the breakdown of good vs bad line-chart design choices. Render the small-multiples grid as the main visual: 6 side-by-side mini panels in 2 rows x 3 columns, each with sharp x- and y-axis labels, clear tick marks, and concise English panel titles. Each panel compares a "Best practice" line example in green versus a "Common mistake" line example in red, with hand-drawn annotation arrows and sketchnote circles. Panel topics: "Start Y-axis at zero when meaningful", "Use direct labels instead of cluttered legends", "Limit the number of lines", "Highlight the key series", "Keep time intervals consistent", "Avoid chartjunk and heavy smoothing". Include realistic plausible illustrative values exactly labeled as illustrative, such as time points "2019, 2020, 2021, 2022, 2023, 2024" and y-axis ranges like "0, 20, 40, 60, 80, 100" where appropriate; do not truncate axes misleadingly or manipulate scale. Add 4 key insight callouts around the grid, each with a headline number, a short interpretation in English, and a small icon: "6 rules" — "Core checks for readable line charts" with a checklist icon; "2 colors" — "Use contrast to separate good and bad examples" with a palette icon; "0 misleading truncation" — "Axes should not exaggerate change" with a warning icon; "1 focus" — "Highlight the most important story, not every series" with a target icon. Add a small bottom strip labeled "Source / Data note" with the text "Illustrative example — figures and mini-chart values are illustrative and not sourced data." Use editorial data journalism illustration, FT / Bloomberg-grade chart aesthetics, vector-clean infographic layout. Visual style: hand-annotated sketchnote with marker notes, tidy notebook feel, high-contrast red and green palette on a clean off-white background, sharp black axes, subtle paper texture, energetic explanatory mood. Include English labels such as "Best practice", "Common mistake", "Time", "Value", "Illustrative", "Direct label", "Too many lines", "Consistent intervals", and "Minimal clutter" quoted exactly as rendered. 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.
