# Visualizations overview

> Create charts, graphs, dashboards, and interactive data visualizations in Sourcetable.

Sourcetable provides multiple ways to visualize your data — from simple bar charts to interactive Sankey diagrams and geographic maps. Create visualizations manually from the toolbar, or describe what you want and let the AI build it.

## Visualization engines

Sourcetable uses three visualization engines, each suited to different use cases:

| Engine           | Best for                                                                                     | Interactivity                              |
| ---------------- | -------------------------------------------------------------------------------------------- | ------------------------------------------ |
| **SourceCharts** | Common charts embedded in the spreadsheet (bar, line, donut, scatter, polar, combo)          | Basic — hover tooltips, legend toggle      |
| **ECharts**      | Advanced charts with animations and rich interactivity (heatmaps, Sankey, tree maps, gauges) | High — zoom, pan, brush select, animations |
| **Plotly**       | Statistical and scientific charts, pivot visualizations, 3D plots                            | High — zoom, pan, hover details, export    |

The AI selects the best engine automatically based on what you ask for. You can also specify a preference.

## Creating visualizations

### With AI (recommended)

Open the AI chat (`Cmd+\` / `Ctrl+\`) and describe the visualization:

* "Create a bar chart of revenue by quarter"
* "Show a heatmap of correlations between all numeric columns"
* "Build a Sankey diagram showing customer journey from signup to purchase"
* "Make a candlestick chart of AAPL stock price for the last 6 months"

### From the toolbar

1. Select your data range (including headers)
2. Click **Insert > Chart**
3. Choose a chart type
4. Configure axes, series, colors, and labels in the chart editor

## Modifying visualizations

After creating a chart, ask the AI to modify it:

* "Change the colors to a warm palette"
* "Add data labels showing percentages"
* "Switch to a stacked bar chart"
* "Add a trend line"
* "Make the y-axis logarithmic"
