If you remove the y.domain here, the chart works in preview but crashes in node tests. I don't understand what the difference might be.

This is how the chart looks like in preview. But it crashes in node. Is apache-arrow behaving differently in the browser?

OK the test is now fixed — I just don't use a file and generate the arrow structure on the fly.

marks: [
Plot.ruleX([0]),
Plot.ruleY(
table,
Plot.normalizeX("sum", {strokeWidth: 2, y: "height", x: "frequency", tip: {format: {y: ".2f"}}})
)
]
});
}
