The dense interval option on the area mark seems to require the y option #2328
Description
I expect this to work:
Plot.areaY(data, {x: "date", reduce: "count", interval: "day"}).plot()After all, it works for a line:
Plot.lineY(data, {x: "date", reduce: "count", interval: "day"}).plot()Instead it seems you have to set the y option to anything:
Plot.areaY(data, {x: "date", y: true, reduce: "count", interval: "day"}).plot()
