Use this visualization tool to turn a clearly structured series or category dataset into an inspectable chart with explicit labels and presentation settings.

Table data

Required object input.

Category field

Required string input.

Value field

Required string input.

Create a portable pie- or donut-chart document from a category column and nonnegative numeric values in tool.io tabular data. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Pie chart document

The resulting pie chart document returned as an object.

• A chart preserves the supplied values but can still mislead through unsuitable chart type, truncated axes, inconsistent scales, excessive categories, missing uncertainty, or inaccessible color choices.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Keep the underlying table available, label units and scales, and choose a chart form that matches the comparison. Add uncertainty intervals or annotations when the data supports them.

• Bar Chart

  Create a portable bar-chart document from two columns of tool.io tabular data.

• Line Chart

  Create a portable line-chart document for ordered observations, with optional series grouping and explicit missing-value behavior.

• Chart

  Create a renderer-independent chart document from portable tabular data and a declarative chart specification.
