/**
 * Collection of settings for symbols, e.g. for scatter plots or legends.
 *
 * The intention is to scale each symbol type so that its area, given a
 * radius parameter, is equal to the area of circle with that radius.
 *
 * Some symbols are additionally scaled slightly with a 'visual factor'.
 * This balances a visual perception effect, where for example triangles with
 * area A can appear larger visually than circles with the same area A.
