Parallel Coordinates Plot in plotly.js
How to make D3.js-based parallel coordinates plots in Plotly.js.
Parallel coordinates are richly interactive by default. Drag the lines along the axes to filter regions and drag the axis names across the plot to rearrange variables: 
var trace = {
type: 'parcoords',
line: {
color: 'blue'
},
dimensions: [{
range: [1, 5],
constraintrange: [1, 2],
label: 'A',
values: [1,4]
}, {
range: [1,5],
label: 'B',
values: [3,1.5],
tickvals: [1.5,3,4.5]
}, {
range: [1, 5],
label: 'C',
values: [2,4],
tickvals: [1,2,4,5],
ticktext: ['text 1','text 2','text 4','text 5']
}, {
range: [1, 5],
label: 'D',
values: [4,2]
}]
};
var data = [trace]
Plotly.plot('graphDiv', data);
Plotly.d3.csv('https://raw.githubusercontent.com/bcdunbar/datasets/master/iris.csv', function(err, rows){
