Infografika US Dollar Features pro výpočet měny

Card grid infographic titled "US Dollar Features". 8 uniform cards in a clean grid, each with a clear central icon/diagram, a name in English with accurate currency code where relevant, and a one-line description in English. Topic focus: generic visual features of the United States dollar, using simplified non-copyrighted banknote representations only, no real banknote face reproductions. Include cards such as: USD code, dollar symbol $, banknote denominations, coin denominations, portrait placement concept, security thread concept, serial number concept, Federal Reserve seal concept. Minimal flat style, minimal monochrome palette, clean vector shapes, high legibility, editorial reference-poster illustration. Visually hint at currency calculation/search intent through subtle calculator, exchange arrows, or numeric layout motifs, but keep all on-image text in English only. 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 real brand logos, no watermarks Generic banknote representations — no copyrighted real banknote face reproductions. Currency codes accurate.
