/**
 * The Auto Viz entry: filter chart types by expressiveness, rank the survivors
 * by effectiveness, and produce a complete, directly-appliable IChart for each
 * legal candidate.
 *
 * When `fields` is empty and `allFields` is provided, the cold-start mode kicks
 * in: instead of greying everything out, each chart type reverse-matches a
 * minimal legal field combination from `allFields`, so an empty canvas becomes
 * a "click anything to start" palette. Matched fields are surfaced on the item
 * as `matchedFields`.
 *
 * `items` always contains every chart type in palette order, so the UI can
 * render unavailable ones greyed out with their disable reason.
