show checkbox inside node while hovering on that node - javascript

I wanted to show the checkbox when hovering on the node so that when the checkbox is clicked the name of that node should be shown at the top of the spider graph and if unticked then that name should disappear.
I used the mouseover event to show the checkbox but is not working
.on("mouseover", function(d) {
d3.select(this).transition()
.duration(200)
.style('cursor', 'pointer')
.html('<input type="checkbox" name="name" class="checkbox" />')
})
Here is the full code with demo

Since the input element is not an svg element, you cannot simply insert a checkbox like and make it work like an html element. We would have to make use of foreignObject and append the input inside it.
Once you create those small rects, we need to append a foreignObject containing our checkboxes and hide them initially like so:
// topic rect
node
.append("rect")
.attr("height", (d, i) => d.parent && d.parent.parent ? 15 : rectangleHeight)
.attr("width", (d, i) => d.parent && d.parent.parent ? 15 : rectangleWidth(d))
.attr("rx", (d, i) => d.parent && d.parent.parent ? 5 : 5)
.attr("ry", (d, i) => d.parent && d.parent.parent ? 5 : 5)
node.append('foreignObject').attr('width', '40')
.attr('height', '40').append('xhtml:input')
.attr('type', 'checkbox').style('display', 'none')
// An on click function for the checkboxes
.on("click",function(d){
console.log(d)
});
When the user hovers over the rects we can then simply unhide the checkboxes, and hide them again if they are not checked (else keep showing until user unchecks) :
.on("mouseover", function(d) {
d3.select(this).select('input').style('display', '');
})
.on('mouseout', function(d) {
if (!d3.select(this).select('input').property('checked')) {
d3.select(this).select('input').style('display', 'none');
}
});

How do I fix zoomable-icicle so that is show some graphics?

Why doesn't this work. There is no error:
The example is taking from this site: https://observablehq.com/#d3/zoomable-icicle
All code is here. It's only html and Javascript. What am I overlooking:
So far it looks like the return of the svg is not working og the color definition is wrong.

Programmatically open nested, collapsed (hidden) nodes in d3.js v6

A follow-on question / issue to
Programmatically open nested, collapsed (hidden) node in d3.js v4
updated for d3.js v6. The issue is the loading of external JSON data in the d3 collapsible menu visualization, and the programmatic access of nested (collapsed, hidden) nodes.
It appears that "treeData", which is the loaded Object, is not being delivered.
Uncaught ReferenceError: treeData is not defined

The treeData variable can be used only in the scope of the function where it's defined as an argument:
d3.json("https://...json")
.then(function(treeData) {
// Scope of the function, treeData can be used here
});
// Out of scope, treeData is not defined
The solution is to move the block that starts with const findNodeAncestors... (~25 lines) inside the function body (right after the last occurence of update with a closing brace):
update(d);

Rotate D3 tree from vertical to horizontal

I am new in D3 and developing a family tree using d3v4(for some constraints not using latest version of d3. Though I am using latest d3 cdn but my requirement is d3v4). The family tree is vertical i.e., parent is in top and children are in bottom. But I want to turn the tree and want to make it horizontal i.e., parent is in left and children are in right.

Nest same object n times in array

Here is an example object array I'd like to transform into a much more complex structure:
[
{
"name": "Blue (3/8)"
},
{
"name": "Green (5/8)"
}
]
To give some context, I am trying to create a visual tree diagram demonstrating the probabilities of different-colored marbles being drawn out of a bag (that's why you see a number followed by a fraction). Below is the statistical-type tree I'm referring to.
I need to repeat adding this same array into an object in a nested format, assigning it to a key titled "children". This needs to be done n amount of times (based on the number of marble draws). The below object would be a result of nesting the same object array 3 times and then it would make a nice tree (using d3.js):
var treeData =
{
"children": [ // Level 1
{
"name": "Blue (3/8)",
"children": [ // Level 2
{ "name": "Blue (3/8)",
"children": [ // Level 3
{ "name": "Blue (3/8)" },
{ "name": "Green (5/8)" }
]
},
{ "name": "Green (5/8)",
"children": [ // Level 3
{ "name": "Blue (3/8)" },
{ "name": "Green (5/8)" }
]
}
]
},
{
"name": "Green (5/8)",
"children": [ // Level 2
{ "name": "Blue (3/8)",
"children": [ // Level 3
{ "name": "Blue (3/8)" },
{ "name": "Green (5/8)" }
]
},
{ "name": "Green (5/8)",
"children": [ // Level 3
{ "name": "Blue (3/8)" },
{ "name": "Green (5/8)" }
]
}
]
}
]
};
// set the dimensions and margins of the diagram
var margin = {top: 20, right: 90, bottom: 30, left: 90},
width = 660 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
// declares a tree layout and assigns the size
var treemap = d3.tree()
.size([height, width]);
// assigns the data to a hierarchy using parent-child relationships
var nodes = d3.hierarchy(treeData, function(d) {
return d.children;
});
// maps the node data to the tree layout
nodes = treemap(nodes);
// append the svg object to the body of the page
// appends a 'group' element to 'svg'
// moves the 'group' element to the top left margin
var svg = d3.select("body").append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom),
g = svg.append("g")
.attr("transform",
"translate(" + margin.left + "," + margin.top + ")");
// adds the links between the nodes
var link = g.selectAll(".link")
.data( nodes.descendants().slice(1))
.enter().append("path")
.attr("class", "link")
.attr("d", function(d) {
return "M" + d.y + "," + d.x
+ "C" + (d.y + d.parent.y) / 2 + "," + d.x
+ " " + (d.y + d.parent.y) / 2 + "," + d.parent.x
+ " " + d.parent.y + "," + d.parent.x;
});
// adds each node as a group
var node = g.selectAll(".node")
.data(nodes.descendants())
.enter().append("g")
.attr("class", function(d) {
return "node" +
(d.children ? " node--internal" : " node--leaf"); })
.attr("transform", function(d) {
return "translate(" + d.y + "," + d.x + ")"; });
// adds the circle to the node

This happens to be the format of the object needed for d3.js to display the desired output in a tree. Here is the closest thing I could salvage to get my desired output:
var objectArray = [{
name: "Blue (5/8)"
}, {
name: "Green (3/8)"
}, {
name: "Blue (5/8)"
}, {
name: "Green (3/8)"
}, {
name: "Blue (5/8)"
}, {
name: "Green (3/8)"
}];
var newArr = objectArray.reverse().reduce((acc, item) => {
return [{
...item,
children: acc
}]
});
console.log(newArr);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
You could take a simple mapping with a look for the wanted depth.
const
create = (data, depth) => data.map((o, i) => ({
name: `${o.name} (${o.count}/${o.total})`,
...(depth > 1 ? { children: create(data.map(({ name, total, count }, j) => ({ name, count: count - (i === j), total: total - 1 })), depth - 1) } : {})
})),
data = [{ name: "Blue", count: 3, total: 8 }, { name: "Green", count: 5, total: 8 }],
result = create(data, 3);
console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }
You can use a recursive function:
const probabilityDrawingMarblesWithoutReplacement = ( marbles, remainingDraws ) => {
let totalMarbles = 0;
for ( let colour in marbles )
{
totalMarbles += Math.max( marbles[colour], 0 );
}
const output = [];
for ( let colour in marbles )
{
const amount = marbles[colour];
if ( amount <= 0 )
{
continue;
}
const colourOutput = {
"name": `${colour} (${amount}/${totalMarbles})`
}
if ( remainingDraws > 1 )
{
const remainingMarbles = Object.assign( {}, marbles );
remainingMarbles[colour]--;
colourOutput.children = probabilityDrawingMarblesWithoutReplacement( remainingMarbles, remainingDraws - 1 );
}
output.push( colourOutput );
}
return output;
}
console.log( probabilityDrawingMarblesWithoutReplacement( {"blue":3,"green":5}, 4 ) );
.as-console-wrapper { max-height: 100% !important; top: 0; }

This is as close I have got so far.. I've merged the two charts together as such - although there is a bug still trying to update the bubbles -- at least get them to scale/morph/move/animate. Ideally I want them to stick close to their group segments..
here is the fiddle.

I thought I will try and first plot mid dot points on the arcs -- and maybe from THOSE -- start to get a batch of zone coordinates to master control the coloured bubbles.
I've been trying to follow this -- How to get coordinates of slices along the edge of a pie chart?
https://jsfiddle.net/tk5xog0g/28/
/*placing mid dots*/
var midDotsArrayCooridnates = [];
slice
.each(function(d) {
x = 0 + (radius * 0.85) * Math.cos(d.startAngle);
y = 0 + (radius * 0.85) * Math.sin(d.startAngle);
var obj = {
"x": x,
"y": y
}
midDotsArrayCooridnates.push(obj);
});
$.each(midDotsArrayCooridnates, function(index, value) {
var dot = doughpie.select(".slicedots").append('circle')
