Tutorials

Tutorials build complete, runnable charts and explain what each action adds. Choose the visual relationship that matches the question you want to answer.

Choose the right authoring level

Choose the smallest action that expresses the intended chart change.

createScatterPlot createPointMark editPointMark

Scatterplot

Compare two quantitative fields and encode a category with color.

createScatterPlot

Polar points

Map quantitative fields to clockwise angle and radial distance.

encodeTheta encodeR encodePointRadius

Polar lines

Connect ordered angle and radial values as grouped open paths.

createLineMark encodeTheta encodeR

Donut chart

Build proportional sectors with an inferred categorical color legend.

createArcMark encodeTheta encodeColor

Line chart

Aggregate values over time and split the result into series.

createLinePlot

Histogram

Bin a quantitative field and count category partitions.

createHistogram

Bar chart

Aggregate ordinal categories and arrange nominal groups side by side.

createBarPlot

Regression scatterplot

Layer observations, grouped fits, and confidence bands.

createPointMark createRegression

Density area

Estimate grouped distributions and draw baseline-closed areas.

createAreaMark encodeDensity encodeColor

Horizon chart

Compress a long time series by folding values above and below a baseline.

createAreaMark encodeHorizon editHorizon

Error bar

Keep observations visible while summarizing group uncertainty.

createErrorBar

Error band

Show interval ribbons with explicit lower and upper boundaries.

createErrorBand

Mark selection and highlighting

Select, filter, and emphasize final point, bar, and line items.

highlightMarks

Area with an explicit baseline

Define bounds and independently revise series identity, placement, and color.

createAreaPlot layoutSeries encodeGroup

Dumbbell changes

Named before and after endpoints retain their roles when values reverse.

createDumbbellPlot

Empirical cumulative distribution

Step-after lines show cumulative probability at each observed support value.

createECDFPlot

The bar tutorial uses grouped bars as one layout of the general bar mark. The statistical tutorials compose ordinary data, marks, encodings, and guides rather than introducing a separate renderer path.
