The Unpaid Backbone of Open Source: Solo Maintainers Face Increasing Security Demands
Solo open source maintainers face burnout and security challenges, with 60% unpaid and 60% considering quitting.
D3Funnel is an extensible, open-source JavaScript library for rendering funnel charts using the D3.js library.
D3Funnel is focused on providing practical and visually appealing funnels through a variety of customization options. Check out the examples page to get a showcasing of the several possible options.
To use this library, you must include the source files for D3.js and D3Funnel.
<script src="/path/to/d3.min.js"></script>
<script src="/path/to/d3-funnel.js"></script>
You must also create a container element and instantiate a new chart:
<div id="funnel"></div>
<script>
var data = [
['Plants', 5000],
['Flowers', 2500],
['Perennials', 200],
['Roses', 50]
];
var options = {};
var chart = new D3Funnel('#funnel');
chart.draw(data, options);
</script>
Option | Description | Type | Default |
---|---|---|---|
width | The pixel width of the chart. | int | Container's width |
height | The pixel height of the chart. | int | Container's height |
bottomWidth | The percent of total width the bottom should be. | float | 1 / 3 |
bottomPinch | How many sections to pinch on the bottom to create a "neck". | int | 0 |
isCurved | Whether the funnel is curved. | bool | false |
curveHeight | The curvature amount (if isCurved is true ). | int | 20 |
fillType | Either "solid" or "gradient" . | string | 'solid' |
isInverted | Whether the funnel is inverted (like a pyramid). | bool | false |
hoverEffects | Whether the funnel has effects on hover. | bool | false |
dynamicArea | Whether block areas are calculated by counts (as opposed to static height). | bool | false |
minHeight | The minimum pixel height of a block. | int/bool | false |
animation | The load animation speed in milliseconds. | int/bool | false |
label.fontSize | Any valid font size for the labels. | string | '14px' |
label.fill | Any valid hex color for the label color | string | '#fff' |
onItemClick | Event handler if one of the items is clicked. | function | function(d, i) {} |
You can specify overriding colors for any data point (hex only):
var data = [
['Teal', 12000, '#008080' '#080800'],
['Byzantium', 4000, '#702963'],
['Persimmon', 2500, '#ff634d' '#6f34fd'],
['Azure', 1500, '#007fff' '#07fff0']
// Background ---^ ^--- Label
];
If you want to pass formatted values to be shown in the funnel, pass in an array containing the value and formatted value:
var data = [
['Teal', [12000, 'USD 12,000']],
['Byzantium', [4000, 'USD 4,000']],
['Persimmon', [2500, 'USD 2,500']],
['Azure', [1500, 'USD 1,500']]
];
