    // 1) Select your `body` and append a `div` element in which you'll render your content. To do this, you'll use the `d3.select()` method, and then the `.append()` method to append your element to your selection.
  
var p = d3.select('body').append('p').text('My Bar Graph!')

// 2)  Append a new `p` element to the `div` you just created, and use the `.text()` method to set the text to "My Bar Chart"
var div = d3.select('body').append('div')
    // 3)  Append a container `svg` to your `div` element in which you'll place your rectangles     
    // - Set your svg's `width` to 300, and `height` to `400`

var svg = div.append('svg')
	.attr('width', 300)

// 4)  Append 3 `rect` elements inside of your `<svg>` (one at a time), setting the properties for each one. We'll improve on this process later: 
    //     - `x`: How far to move the rectangle in the `x` direction (right). Should be `0` for all rectangles. 
    //     - `y`: How for to move the rect in the `y` direction (down from the top). Should be `10`, `40` `70` 
    //     - `width`: How far to draw the rectangle to the right. Should be `100`,`200`, `300` 
    //     - `height`: The vertical height of each rectangle. Should be `20` for all rectangles
