Apache Superset Pricing Line Chart Best Practices Infographic

Data visualization infographic titled "Line Chart Best Practices" using a TREND LINE (over time) presented as a small-multiples grid, with the chart as the dominant visual element: a 2x3 grid of mini line charts comparing six example time series across "Month" on the x-axis and "Value" on the y-axis, all axis labels, tick marks, legends, captions, and annotations in sharp English text. The central storytelling angle is show the surprise / outlier: five panels demonstrate good line-chart behavior and one panel highlights a dramatic outlier spike clearly and honestly. Include explicit best-practice visual cues: consistent scales across comparable panels, zero-baseline note where appropriate, no misleading axis truncation, readable tick spacing, direct end labels, restrained gridlines, and highlighted anomaly marker. Use realistic plausible illustrative numbers only, clearly labeled as illustrative. Example panel titles in exact English: "Stable Growth", "Seasonal Pattern", "Gradual Decline", "Volatile but Flat", "Outlier Spike", "Recovery Trend". Example x-axis labels: "Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec". Example y-axis label: "Index Value (illustrative)". Example end labels and ticks should be crisp and readable, with plausible values such as 20, 40, 60, 80, 100, 120. In the "Outlier Spike" panel, show a line mostly ranging 38-52 with one sudden jump to 118 in "Aug", marked with a contrasting dot and annotation in exact English: "Unexpected spike". Add 4 key insight callouts around the grid, each with a headline number, short interpretation in English, and a small icon: 1) "118" — "Largest illustrative outlier appears in Aug" with alert icon; 2) "6 panels" — "Small multiples reveal pattern differences instantly" with grid icon; 3) "Same scale" — "Consistent axes prevent misleading comparisons" with ruler icon; 4) "12 months" — "Full timeline preserves context around anomalies" with calendar icon. Include a compact best-practice checklist sidebar in English with exact labels such as "Use consistent scales", "Label anomalies directly", "Avoid truncated axes", "Keep gridlines subtle", "Compare like with like". Add a small SOURCE / DATA-NOTE strip in English at the bottom with exact text: "Data note: Illustrative example for design best practices only. Figures are illustrative unless sourced by the user." Do not cite any fake publication or authority. Visual style: dark dashboard interface, FT pink and deep navy palette with soft magenta highlights, charcoal background, subtle thin gridlines, glowing anomaly accent, modern newsroom aesthetic, high contrast but elegant. Overall mood: analytical, polished, surprising but trustworthy. 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.
