| [lineCap](#linecap) | string | 'butt' | Style of the line endpoints. The options are as follows:<br/>- **'butt'**: The endpoints of the line are squared off.<br/>- **'round'**: The endpoints of the line are rounded.<br/>- **'square'**: The endpoints of the line are squared off by adding a box with an equal width and half the height of the line's thickness. |
| [lineJoin](#linejoin) | string | 'miter' | Style of the shape used to join line segments. The options are as follows:<br/>- **'round'**: The shape used to join line segments is a rounded corner with the radius equal to the line width.<br/>- **'bevel'**: The shape used to join line segments is a beveled corner. The rectangular corner of each line is independent.<br/>- **'miter'**: The shape used to join line segments is a mitered corner. The corner is formed by extending the outside edges of the lines until they meet. You can adjust the effect of this attribute using **miterLimit**. |
