Chart types

Chart types — overview, shared editor settings, and links to each chart type reference in Toucan AI.

Target Audience: Non-technical users and builders configuring visualizations in the Library.

Overview

Toucan AI supports several chart types in the Library manual editor. Each type has its own dimension, measure, and display options. Use the pages below when you refine a chart after AI creation or build one from scratch in Manual Edit mode.

Prerequisites

• A connected and active database.

• A Data source (database and query) selected in the chart editor.

Chart type reference index

Page	Use case
Bar chart	Compare categories or rankings
Stacked bar chart	Part-to-whole breakdown within categories
Line chart	Trends over time or by category
Circular chart	Share of a whole (pie / donut)
Heatmap chart	Two dimensions with cell intensity
Value	Single KPI with optional variation
Table	Tabular data with column-level formatting

Shared chart-level settings

All chart types share these fields at the top of the manual editor:

Option	Description
Title	Name shown in the Library and embeds.
Narrative	Optional explanation for end users.
Data	Database and query that supply columns for the chart.

Shared measure options

Where a chart uses a metric column (Bars, Line, Value, etc.), you can usually set:

• Aggregation (Sum, Average, Count rows, etc.). Options depend on column type.

• Format number — decimals, percent, currency, and Unit for numeric columns.

See each chart page above for the exact fields available.
