BrazilMap
Every example on this page is live, drawn by the library's Storybook, where you can also change its props and see the result.
A monochromatic SVG map of Brazil, shading its 27 federative units (26 states and 1 federal district) using fill patterns and optional numeric labels. Uses a Mercator projection. The map keeps its proportions, filling as much of its box as it can and centered in the rest, in any box it is laid out in.
Import
import { BrazilMap } from "~lib/data-display/maps/brazil-map";
Props

height | number | "fill" | string | No | 340 | Component height (px or CSS string), or "fill" to be as tall as its width makes it at the map's proportion |
BrazilStateName
27 federative units. Examples: "São Paulo", "Rio de Janeiro", "Minas Gerais", "Bahia", "Amazonas", "Ceará", "Goiás".
BrazilMapEntry
type BrazilMapEntry = {
shading: "solid" | "diagonal" | "dots" | "crosshatch";
value?: number;
};
MapMarker
type MapMarker = {
latitude: number;
longitude: number;
label?: string;
shape?: "circle" | "square" | "triangle" | "diamond"; // "circle" by default
};
type MapLegendEntry = {
shape: "circle" | "square" | "triangle" | "diamond";

With Markers
markers puts a dot on each place you give, with its label beside it where there is room, and a marker's shape draws it as a square, a triangle or a diamond instead, which legend names under the map. height="fill" makes the box as tall as its width makes it at the map's proportion. See WorldMap for how labels are placed, how the legend gives way and how a filled map shrinks.
