+# Pull request template #1
+## For adding a new component with status `Baseline completed`
+
+A component's status should be updated to `Baseline completed` when the core functionality for the component has been completed and it is ready for use in prototyping. 
+
+`Baseline completed` components have not necessarily passed review for responsive design, accessibility, progressive enhancement and real-use testing. 
+
+Therefore, developers should be prepared that these components may be modified in the future. Where modifications occur, a new version of the component library will be published and a description of the updates will be included in the change log.

+| Description | The `Line` component receives an array of data and a lineFunction and combines them to render an SVG path element. <br><br>This path element can have hover and click events. It can also have markers, which can have their own optional hover and click events. |
+| Context | Since the `Line` component renders an SVG path element it must be called within an `<svg>` element. <br><br>The Line component has been designed as a child component of `Lines`, which takes a full dataset and renders a line for each row, allowing developers to customise the styling and behaviour of lines in groups or individually.<br><br>The Lines component has, in turn, been designed as a child component of `LineChart`, which incorporates other components include `Axis` and labelling to form a complete data visualisation. |
