Set z and color to a series field and layout to group() to place each month's series side by side.

Set layout to stack() to pile the series into one bar per month, rounding only the end of the top segment.

Use barX with the band scale on y to lay the bars out sideways, with the category labels on the left.

Add a text mark on the same x and y and lift it with dy to print each bar's value above it.

Anchor one text mark at zero for the name inside the bar and another at the bar's end for its value.

Set color to the category field to give every bar its own color from the theme palette.

Pass functions to fill, stroke and strokeDasharray to draw one bar with a dashed outline and a lighter fill.

Return a color from fill by sign to paint gains and losses, with labels above or below each bar through dy.

Unpivot three cause columns with fold, then stack() them on a time scale to show monthly totals by cause.

Sort the rows and draw them with barX to rank metro areas by population while keeping long labels readable.

Reduce raw rows to one mean per species with groupBy and a mean output, then label each bar with its value.

Give group() two slots and use y1 and y2 to stack two measures in one slot beside a third bar each day.

Negate one group and pass stack({ offset: "diverging" }) to grow the two sides away from a shared zero line.
