In this lesson.

We're just going to have a quick look at another visualization called the Decomposition Tree.

And this is quite useful if you want to see how the breakdown of an item actually contributes to the

total.

So let's say, for example, we've got our different product categories and we want to see the breakdown

into the product subcategories and into the product name to see which items actually contribute the

most to say, our profit.

Okay, So let's choose our decomposition tree to this visualization over here and let's make it nice

and big again.

Okay, so you see that you could feel free to analyze and explain, but also you got tooltips.

But let's start with the analyzer.

In this case, we're going to be analyzing our profit.

So we're going to pop our profit in there.

And it shows me the total amount of profit that I've got in the data set.

Now, the first way that we're going to analyze this is by different product categories.

So you see I get a little plus option.

And what it allows me to do is to pick, do I want to see this the high value or do I want to see the

low value?

So in this case, I want to see the highest value, and we will have that on the top.

So computers is our highest profit down to our audio.

Now, if we want to break this down further, we might want to say we want to also explain this by our

different product subcategories.

Just drop that in there.

And again, let's just break this down.

Again, they say the high value for this.

So you can see now that you're now showing the path of three computers to projectors and screens.

And you can see then the different profit values that are being displayed for each of these.

So basically the composition of this could actually go one step further.

We could say we want to see the product name as well.

And again, I could break this up.

Let's say we want to see the highest value on top again, and now we have the highest product itself

being displayed as well.

So you could change now the path of this.

You could just say, I want to see within, say, laptops, for example, and now you'll see that it

will show you all of the products for laptops or for desktop, for example, could change this as well.

You could say I want to see for cameras and camcorders and you'll see now that the paths start to change,

the products start to change.

So within digital cameras.

So this is really nice.

If you want to get a visual representation of how something like profit is actually built up.

Let's look at another example.

So we've actually got region, we've got countries and we've got cities.

So let's say for example, we use our region in here.

Explain by use our countries.

Drop that in the inner cities and you should see the same type of logic.

So if we want to see which country makes the most amount of profit, go over here as well, we'll say

we want to see the high value.

So the high value is North America again, if we want to see the details of this at the highest country,

we know the United States is.

And again, if we want to now see the highest city, then it will show us the highest city through that.

And again, if we want to change the path, then we could say we want to see within Asia, we can see

China makes the most maybe in Australia, we're interested to know what is the actual highest on this.

Sometimes when you click on it, it doesn't always respond.

But there we go.

We got it to work.

So we've got Australia now we can see that Sydney actually makes the highest.

So as I say, really interesting sort of visualisation.

If you want to be able to go through and be able to see the composition of something such as profit

and how it's made up and it's also quite interactive.

So there we go.

That is the decomposition visualization.

I will see you in the next lesson.
