I am working on a d3js horizontal chart - the designers are specific in having the labels this way.
I've built the following - but would like to model it more on older code that had animation properties.
//current chart

Do you want the horizontal chart to have an initial animation on load?
– Robert Andersson
17 hours ago
yes - but also be able to animate if the data changes
– The Old County

That would require a bit of refactoring, do you need to use version 3 of d3 or can you use the latest version?
– Robert Andersson
17 hours ago
it could be the later version - how does it matter?

The d3 methods etc have slightly different names in the later version amongst other things, that's why I asked. I'll post an answer soon

I had a similar chart that I've made a few modifications to that might fill your requierments, so I'll be basing my answer of my own code.
I'll just go through the most relevant part of the question and you can just have a look at the code and hopefully figure out how it works yourself.
The inital animation works exactly the same way as in the third link you posted:
.transition().duration(speed)
.delay((_, i) => delay * i)
we set a delay so that each bar appear one at a time.
I've also set it up so that you can change the data using the d3js update pattern.
var bar = svg.selectAll(".bar")
.data(data, d => d.name)
bar.exit().remove();
bar.enter().insert("g", ".y-axis").append("rect")
.attr("class", "bar")
.attr("fill", "#ccc")
.attr("x", x(0))
.attr("y", d => y(d.name))
.attr("height", y.bandwidth())
.merge(bar)
.transition().duration(speed)
.delay((_, i) => delay * i)
.attr("y", d => y(d.name))
.attr("width", d => x(d.value) - x(0));
Since you didn't specify how you want to update the new data it's just a year filter for now.
Here's all the code:
var init = [
{"year": "2017", "name": "Apples", "value": 20},
{"year": "2017", "name": "Bananas","value": 12},
{"year": "2017", "name": "Grapes", "value": 19},

I had a similar chart that I've made a few modifications to that might fill your requierments, so I'll be basing my answer of my own code.
I'll just go through the most relevant part of the question and you can just have a look at the code and hopefully figure out how it works yourself.
The inital animation works exactly the same way as in the third link you posted:
.transition().duration(speed)
.delay((_, i) => delay * i)
we set a delay so that each bar appear one at a time.
I've also set it up so that you can change the data using the d3js update pattern.
var bar = svg.selectAll(".bar")
.data(data, d => d.name)
bar.exit().remove();
bar.enter().insert("g", ".y-axis").append("rect")
.attr("class", "bar")
.attr("fill", "#ccc")
.attr("x", x(0))
.attr("y", d => y(d.name))
.attr("height", y.bandwidth())
.merge(bar)
.transition().duration(speed)
.delay((_, i) => delay * i)
.attr("y", d => y(d.name))
.attr("width", d => x(d.value) - x(0));
Since you didn't specify how you want to update the new data it's just a year filter for now.
Here's all the code:
var init = [
{"year": "2017", "name": "Apples", "value": 20},
{"year": "2017", "name": "Bananas","value": 12},
{"year": "2017", "name": "Grapes", "value": 19},

Do you want the horizontal chart to have an initial animation on load?
– Robert Andersson
17 hours ago
yes - but also be able to animate if the data changes

That would require a bit of refactoring, do you need to use version 3 of d3 or can you use the latest version?
– Robert Andersson
17 hours ago
it could be the later version - how does it matter?

The d3 methods etc have slightly different names in the later version amongst other things, that's why I asked. I'll post an answer soon
