how to get data from nested json file for d3.js? - d3.js

How to get lat, lon, date?
I have used nested but it's not working. lat and lon are showing data in HTML console but unable to use lat and lon to display location as circles in the map.
the issue is in the var nested part. I have tried multiple ways to solve but unable to.
here is the data:
[{
"session":{"id":"1"},
"location":{"lat":36.958992,"lon":-122.045301},
"number":{"created":{"date":"2018-05-19 00:00:51.000000"}},
"session":{"id":"2"},
"location":{"lat":40.958992,"lon":-100.045301},
"number":{"created":{"date":"2018-05-29 00:00:11.000000"}}
}]
here is the code I have used:
it is html file with everything;

How to build a zoomable choropleth map with insets to handle discrete data in d3.v5?

Very new to D3 and coming from R but looking to develop some interactive choropleth maps.
I'm wanting to develop this zoomable choropleth: https://bl.ocks.org/cmgiven/d39ec773c4f063a463137748097ff52f
into something like this V5 choropleth with easily attachable data: https://bl.ocks.org/denisemauldin/3436a3ae06f73a492228059a515821fe
I can mainipulate the V5 choropleth fairly easily, still figuring out how to adjust continuous scale to a discrete scale but I don't really know how to build the zoomable svg in V5.

I think in your question you are asking about continuous scale, here is a code snippet for continuous scaling for an zoomable choropleth, What is just apply the same mechanism in this bl.ocks.org just wrap everything in <g> group tag and apply the zoom on this <g> tag:
const zoom = d3.zoom()
.scaleExtent([1, 8])
.on('zoom', zoomed);
svg.call(zoom);
function zoomed() {
zoomG.selectAll('path') // To prevent stroke width from scaling
.attr('transform', d3.event.transform);
}
var svg = d3.select("svg"),
width = +svg.attr("width"),
height = +svg.attr("height");
var unemployment = d3.map();
var stateNames = d3.map();
var path = d3.geoPath();
var x = d3.scaleLinear()
.domain([1, 10])
.rangeRound([600, 860]);
var color = d3.scaleThreshold()
.domain(d3.range(0, 10))
.range(d3.schemeBlues[9]);
var g = svg.append("g")
.attr("class", "key")
.attr("transform", "translate(0,40)");
g.selectAll("rect")
.data(color.range().map(function(d) {
d = color.invertExtent(d);
if (d[0] == null) d[0] = x.domain()[0];
if (d[1] == null) d[1] = x.domain()[1];
return d;
}))
.enter().append("rect")
.attr("height", 8)
.attr("x", function(d) { return x(d[0]); })
.attr("width", function(d) { return x(d[1]) - x(d[0]); })
.attr("fill", function(d) { return color(d[0]); });
g.append("text")
.attr("class", "caption")
.attr("x", x.range()[0])
.attr("y", -6)
.attr("fill", "#000")
.attr("text-anchor", "start")
.attr("font-weight", "bold")
.text("Unemployment rate");
g.call(d3.axisBottom(x)
.tickSize(13)
.tickFormat(function(x, i) { return i ? x : x + "%"; })
.tickValues(color.domain()))
.select(".domain")
.remove();

How to use hover and add text over node in d3 force simulation

I am trying to make d3 force simulation where i am parsing data from csv file and i am trying use hover and showing text over node but i am unable to show it though i am able to parsing csv file.
Here is my code:
<!DOCTYPE html>
<meta charset="utf-8">
<style>
.link {
stroke: #000;
}
.node {
stroke: #fff;
}
</style>
<body>
<script src="http://d3js.org/d3.v3.min.js" charset="utf-8"></script>
<script>
var width = 960,
height = 500;
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height);
var force = d3.layout.force()
.size([width, height]);
d3.csv("data.csv", function(error, links) {
if (error) throw error;
var nodesByName = {};
// Create nodes for each unique source and target.
links.forEach(function(link) {
link.source = nodeByName(link.source);
link.target = nodeByName(link.target);
});
// Extract the array of nodes from the map by name.
var nodes = d3.values(nodesByName);
// Create the link lines.
var link = svg.selectAll(".link")
.data(links)
.enter().append("line")
.attr("class", "link");
// Create the node circles.
var node = svg.selectAll(".node")
.data(nodes)
.enter().append("circle")
.attr("class", "node")
.attr("r", 4.5)
.call(force.drag);
// Start the force layout.
force
.nodes(nodes)
.links(links)
.on("tick", tick)
.start();
function tick() {
link.attr("x1", function(d) { return d.source.x; })
.attr("y1", function(d) { return d.source.y; })
.attr("x2", function(d) { return d.target.x; })
.attr("y2", function(d) { return d.target.y; });
node.attr("cx", function(d) { return d.x; })
.attr("cy", function(d) { return d.y; });
}
function nodeByName(name) {
return nodesByName[name] || (nodesByName[name] = {name: name});
}
});
</script>
Here, Is my output
Actually, I am new in d3 force simulation, any suggestion is highly appreciated.
Thanks

Perhaps this would work,
var node = svg.selectAll(".node")
.data(nodes)
.enter().append("circle")
.attr("class", "node")
.attr("r", 4.5)
.on("mouseover", handleMouseOver)
.on("mouseout", handleMouseOut);
.call(force.drag);
and then call the functions as in the example here http://bl.ocks.org/WilliamQLiu/76ae20060e19bf42d774

Get bounding box of individual countries from topojson

I want to get bounding boxes for each country from a topojson, but when I add them as svg rectangles they are bundled together towards 0,0.
Ive re-read the API and played around with the order of the bound coordinates, but that didn't change anything! Also, I tried to use the SVG method getBBox() on the country paths but that produced the same result.
Any ideas?

//Generate paths based on projection
var myPath = d3.geoPath().projection(proj);

}
function boundingExtent(features) {
var bounds= [];
for (var x in features) {
var boundObj = {};
thisBounds = myPath.bounds(features[x]);
boundObj.id = features[x].id;
boundObj.x = thisBounds[0][0];
boundObj.y = thisBounds[0][1];
boundObj.width = thisBounds[1][0] - thisBounds[0][0];
boundObj.height = thisBounds[1][1] - thisBounds[0][1];
boundObj.path = thisBounds;
bounds.push(boundObj)
}
return bounds;
}
function boundExtentBySvg(){
var countries = svg.selectAll(".country")
countries.each(function(d){
var box = d3.select(this).node().getBBox();
bboxes.push({id: d.id, x: box.x, y : box.y, width: box.width, height : box.height})
})
}

In these lines:
.attr("x1", function(d) {
return d.x;
})
.attr("y1", function(d) {
return d.y;
})
rect does not have an attribute of x1 or y1, I think you meant just x and y.

D3.js How to hide/show line when click select options?

I tried to use D3.js to draw lines when you click on different checkbox. It will get data of that option. Here is an example I used D3 multi-series line chart with tooltips and legend. I have got the specific data object that is corresponding the checkbox I choose. Howevery, I don't know how to draw it on svg. Please help me and I will appreciate you so much.
I also find a website "www.cotrino.com/starpaths/" that shows the final effect I want to implement.

You need to create your line variable:
var myLine = svg.append("path");
And then, inside redraw(), changing it according to the option selected:
myLine.datum(adata.values)
.attr("d", line);
Here is a demo plunker: https://plnkr.co/edit/YjGO9TLDBXj13JQuO5bm?p=preview
PS: I changed your x-scale range:
var x = d3.scaleTime().range([margin.left, width]);
And also added a call to redraw() when the code runs for the first time.

how to zoom only map and smiley could stay at same place and size

I having problem of zoom over map. The actual problem is when i zoom map, the location showing on map using smiley could also zoom but i don't want to zoom smiley. It could stay at same size and place. Sometime smiley get overlap so to avoid this i am trying to solve the above problem but i don't have idea how to transform attribute contains many things like images and text on map of d3.js. Please have a look at jsfiddle link and you can see that at japan 3 smiley get overlap and keep overlapped even after zooming map.
My JSfiddle link
my code is following:
<!DOCTYPE html>

Any body help me to zoom only map image not smiley

Implement semantic zooming :)
Try use this example to change your code :) :
Semantic zoom on map with circle showing capital
JSFIDDLE : http://jsfiddle.net/xf7222dg/2/
The code below shrinks the 'circles' depending on scale
var zoom = d3.behavior.zoom()
.on("zoom",function() {
g.attr("transform","translate("+
d3.event.translate.join(",")+")scale("+d3.event.scale+")");
g.selectAll("circle")
.attr("r", function(){
var self = d3.select(this);
var r = 8 / d3.event.scale; // set radius according to scale
self.style("stroke-width", r < 4 ? (r < 2 ? 0.5 : 1) : 2); // scale stroke-width
return r;
});
});
Here is it working with your smileys: http://jsfiddle.net/dmn0d11f/7/
You have to change the 'width' of the nodes (images) not the radius like with the circles. So select the nodes and instead of changing 'r' change 'width' :
g.selectAll(".node")
.attr("width", function(){
var self = d3.select(this);
var r = 28 / d3.event.scale; // set radius according to scale
self.style("stroke-width", r < 4 ? (r < 2 ? 0.5 : 1) : 2); // scale stroke-width
return r;
});
