| Property | Type | Mandatory | Default | Description |
| :----------------- | :----------------- | :-------- | :--------------- | :---------------------------------------------------------------------------------------------- |
| data | object | yes | no | The data to be rendered as a tree |
| nodeWidth | number | no | 100 | Width node container |
| nodeHeight | number | no | 50 | Height node container |
| xOffset | number or function | no | 50 | Distance between adjacent nodes by x |
| yOffset | number | no | 50 | Distance between adjacent nodes by y |
| pathShape | enum or function | no | “bezier” | Defines curve shape, which connects nodes |
| nodeContent | function | yes | no | Node box content. Html element |
| lineClassName | string | no | "connectingLine" | ClassName, defines style of curve shape, which connects nodes |
| nodeBoxClassName | string | no | "nodeBox" | ClassName, defines style of node view |
| direction | enum | no | "forward" | defines building diagram order. If "forward" - root element at left side, "reverse" - at right. |

props description:

nodeWidth, nodeHeight - size of node box in pixels, defined by HTML element size, that return by nodeContent function;

xOffset, yOffset - distance between adjacent nodes. xOffset may be a function with level argument, where level - tree branches level;

pathShape - there are three preset functions: bezier, straight and roundedAngles. Functions return d attribute for tag path as string. Instead, you can pass your function, which accepts following parameters: start x, start y, end x, end y. Corner rounding in roundedAngles function calculates automatically, and it depends on distance between adjacent nodes. As bonus, there is another one preset function - staticRadiusRoundedAngles, which accepts five arguments. Fifth argument - corner rounding radius.

nodeContent - any HTML element or react component.

direction` - diagram order. If "forward" - root element at left side, "reverse" - at right.
