<title>Second Bar Chart Using D3 AND Data Joins!</title> | |
<style> | |
/* Set `rect` elements to have a "fill" of "purple" or whatever color you choose */ | |
rect { | |
fill: purple; | |
} | |
</style> | |
<!--- Load the d3 library --> | |

// - 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 div = d3.select('body').append('div'); | |
// - Append a new `p` element to the `div` you just created, and use the `.text()` method to set the text to "My Bar Chart" | |
div.append('p').text('My Bar Chart') | |
// - 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) | |
.attr('height', 400) | |
// 1) 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 | |
// This is the dataset to drive the layout: | |
var data = [{ | |
y: 10, | |
width: 100 | |
}, | |
{ | |
y: 40, | |
width: 200 | |
}, | |
{ | |
y: 70, | |
width: 300 | |
}, | |
]; | |
