I am very new to Liferay.
I would like to show my graph created by D3.js inside of a portlet.
I have created the default MVC portlet.
However, I have no idea how to show my graph inside a MVC portlet.
Can you please advise?
<!DOCTYPE html>

.chart div {

background-color: steelblue;
text-align: right;
padding: 3px;
margin: 1px;

<script>
var data = [30, 86, 168, 281, 303, 365];
d3.select(".chart")
.selectAll("div")
.data(data)
.enter()
.append("div")
.style("width", function(d) { return d * 2 + "px"; })
.text(function(d) { return '$ ' + d; });

I'm learning D3 and I'm trying to display data infomation on a scatterplot by hovering on the SVG circles. I take the data from a csv file (data is on the Solar System, with planet names, masses and radiuses) and all the circles show up correctly but when I try to console.log the data information (for instance the mass) on mouseover it does not log anything. The mouseover action is functioning OK but the console tells me that the value requested is "undefined".
Where did I mess up? This is my code:
<!DOCTYPE html>
<html lang="en">
<head>
<style type="text/css">
body{
background-color: black;
}
#chart{
background-color: black;
width: 800px;
height: 500px;
border: solid 1px white;
}
svg{
background-color: white;
}
.dot{
stroke: red;
stroke-width: 1px;
}
</style>
<script type="text/javascript" src="https://d3js.org/d3.v6.min.js"></script>
</head>
<body>
<div id="chart"></div>
<script type="text/javascript">
var width = 800;
var height = 500;
var circles;
var svg = d3.select('#chart')
.append('svg')
.attr('width', width + 'px')
.attr('height', height + 'px');
d3.csv('astro.csv').then(function(data){
xScale = d3.scaleLinear()
.domain([0,500])
.range([0, 800]);
circles = svg.selectAll('.dot')
.data(data)
.enter()
.append('circle')
.attr('class', '.dot')
.attr('cx', function(d){
return xScale(d.mass);
})
.attr('cy', 100)
.attr('r', 20)
.on('mouseover', function(d){
console.log(d.mass);
})
});
</script>
</body>

Since D3 V6, all mouse event handlers has an event passed as the first argument and data as the second. In the V5 or earlier, your code will work.
V6 or higher:
.on('mouseover', (event, d) => console.log(d.mass));
V5 or earlier:
.on('mouseover', d => console.log(d.mass));
I have been trying to render a simple two value pie chart using D3.JS v5 in the lower right corner to no avail. Can someone please assist me with this - the code can be found here:

As #Tom Shanley has indicated in the comments, the reason of why your pie chart is not rendered as expected is because you need to create a SVG first.
Notice that I've also changed some CSS properties of #pieChart for improving the snippet visibility, although it is not necessary for your purposes.

Why the result of bBox.width, bBox.height are both 0? I expect them to be both 500px, how to rectify it?

Try getBoundingClientRect instead of getBBox.
I've copied the code below from the example provided here https://scrimba.com/casts/cast-1953
However, no graph is shown. I also get no errors in the console.
When I enter d3 in the console an object is returned, so d3 is found.
What am I missing?

Instead using script in head, try to use at the bottom of the page or use when page is ready.

You must place the body before the script like so:
<body>
<div class="chart"></div>
</body>
<script type="text/javascript" src="https://d3js.org/d3.v4.min.js"></script>
<style type="text/css">
.chart div {
font: 10px sans-serif;
background-color: steelblue;
text-align: right;
padding: 3px;
margin: 1px;
color: white;
}
</style>
<script type="text/javascript">
var data = [30, 86, 168, 281, 303, 365];
d3.select(".chart")
.selectAll("div")
.data(data)
.enter()
.append("div")
.style("width", function(d) {
return d + "px";
})
.text(function(d) {
return d;
});
</script>
I am generating dynamic context menus that appear when the user right clicks on a shape. I have managed to create the context menu, but I am having trouble catching the click event when the user selects an entry from the menu.
The event keeps binding to the right click action to create the context menu instead of a left click on the list items within the menu itself.
I have dug around SO a bunch and been unable to unearth something that will get me the rest of the way.
What I want is for the console.log function in this example to trigger when the user clicks a list element and pass the name of the item clicked. In a perfect world it would not trigger on the initial right click, but I'll take what I can get.

Here is a plunkr demonstrating the code (I can't figure out why I couldn't get it to run with jsfiddle): http://run.plnkr.co/plunks/paPKKlUFtQCGpOmjQztS/
Please see this fiddle
I basically updated your click listener to this:
.on('click' , function(d) { console.log(d); return d; })
It seems to be working fine.
