# --description--
Your dashboard element is now "selected". D3 has a number of functions for working with a selection; one of them is `append`. It is used to add an element. Chain the `append` function to your selection and use it to add an `svg` element. Here's an example of how that might be done:
```js
const variableName = d3.select('selectedElement')
.append('elementToAdd')
```
# --hints--
test-text
```js
assert(lineGraph._groups[0][0] === $('svg')[0]);
```
