```js values = d3.cross(d3.range(10), d3.range(10)).map(([i, j]) => i * j); ``` ```js Plot.plot({ aspectRatio: true, inset: 40, x: { ticks: 10 }, marks: [ Plot.dot(values, { x: (d, i) => i % 10 + 0.5, y: (d, i) => Math.floor(i / 10) + 0.5, fill: (d) => d }), Plot.geo([]) ] }) ``` Note: in that case aspectRatio is not completely ignored, but defaults to the golden ratio.
