--- title: Add Document Elements with D3 --- ## Add Document Elements with D3 [This challenge](https://learn.freecodecamp.org/data-visualization/data-visualization-with-d3/add-document-elements-with-d3) introduces three core methods of **d3.js**: * The `d3.select()` method * The `d3.append()` method * The `d3.text()` method ### The select() Method The select method is crucial, because it tells the browser where to put any _d3.js_ code written afterwords. In _Javascript_, you would write `document.getElementById('#myId');`. In _d3.js_, you would write `d3.select('#myId')`. ### The append() method The append method is similar to _jsx_ in _react_, markup in _html_ or the `appendChild()` method in _Javascript_. For Example, writing `d3.select('#myId').append('p')` would be the same as writing `...

...` ### The text() method The text method is the third step in applying content to a page using _d3.js_. We have selected an element in our html and added an element. Now, we need to fill the empty element. We do that like this: `d3.select('#myId').append('p').text('sup World!')`. This is akin to writing `...

'sup World!

...` in html. ### The Solution Add the folowing code to your editor: ``` d3.select('body') .append('h1') .text('Learning D3'); ```
