A Gantt chart is a type of bar chart, first developed by Karol Adamiecki in 1896, and independently by Henry Gantt in the 1910s, that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project.
Mermaid can render Gantt diagrams.

Styling of the a gantt diagram is done by defining a number of css classes. During rendering these classes are extracted from the
| Class | Description |
|---|---|
| actor | Style for the actor box at the top of the diagram. |
| text.actor | Styles for text in the actor box at the top of the diagram. |
| actor-line | The vertical line for an actor. |
| messageLine0 | Styles for the solid message line. |
| messageLine1 | Styles for the dotted message line. |
| messageText | Defines styles for the text on the message arrows. |
| labelBox | Defines styles label to left in a loop. |
| labelText | Styles for the text in label for loops. |
| loopText | Styles for the text in the loop box. |
| loopLine | Defines styles for the lines in the loop box. |
| note | Styles for the note box. |
| noteText | Styles for the text on in the note boxes. |

}Is it possible to adjust the margins for rendering the gantt diagram.
This is done by defining the ganttConfig part of the configuration object.
How to use the CLI is described in the mermaidCLI page.
mermaid.ganttConfig can be set to a JSON string with config parameters or the corresponding object.
mermaid.ganttConfig = {
titleTopMargin:25,
barHeight:20,
barGap:4,
topPadding:75,
sidePadding:75
}| Param | Descriotion | Default value |
|---|---|---|
| mirrorActor | Turns on/off the rendering of actors below the diagram as well as above it | false |
| bottomMarginAdj | Adjusts how far down the graph ended. Wide borders styles with css could generate unwantewd clipping which is why this config param exists. | 1 |
