That" to get elements having either the this or that class. But what if you want to select children elements? Nested selections to the rescue. selectAll('td'). Both will select all the cells in a table body. Keep in mind that nested selections maintain the hierarchy of selected elements, which gives us some interesting capabilities. Let's look at a short example. Selections example Take the base HTML from our play environment in the first chapter and add a simple table:

One Two Three Four Five
q w e r t
a s d f g
z x c v b

Pretty much the standard markup for a table,


define the head and body of the table where each

is a row and each

is a cell.

Computers handle transformations as matrix multiplication because any sequence of transformations can be collapsed into a single matrix. This means they only have to apply a single transformation that encompasses your sequence of transformations when drawing the shape, which is handy. We will apply transformations with the transform attribute. We can define multiple transformations that are applied in order. The order of operations can change the result. You'll notice this in the following examples.

Two skew transformations exist: skewX and skewY. 2)+') skewY(20)'); We just bolted skewY(20) on to the end of the transform attribute. We have once more destroyed our careful centering. Fixing this is left as an exercise for the reader (I've always wanted to say that). All said, transformations really are just matrix multiplication. In fact, you can define any transformation you want with the matrix() function. I suggest taking a look at exactly what kind of matrix produces each of the preceding effects.
