SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text. Graphical objects can be grouped, styled, transformed and composited into previously rendered objects.

By default, the transform-origin property for SVG elements is normally 0,0 . This means that our bars will be rotated around the top-left corner of the viewport, but we want them to rotate around the center.

Note: The default value of transform-origin is 0 0 for all SVG elements except for root <svg> elements and <svg> elements that are a direct child of a foreignObject, and whose transform-origin is 50% 50% , like other CSS elements.

The scale() function scales a shape up or down in size. The scale() function scales both the shapes dimensions and its position coordinates. Thus, a rectangle positioned at 10,10 with a width of 20 and a height of 30, scaled by a factor of 2 will appear at 20,20 with a width of 40 and a height of 60.

SVG allows modifying graphic elements using translation, rotation, scaling, and skewing. All these SVG transformations refer to the geometric kind. SVG objects can be altering using the transform attribute's properties: translate, scale, rotate, skewX, skewY, and matrix.

The translate matrix combines both tx and ty values to move an element horizontally and vertically. It shifts the object by tx along the x-axis and by ty along the y-axis.

The transform attribute defines a list of transform definitions that are applied to an element and the element's children. Note: As of SVG2, transform is a presentation attribute, meaning it can be used as a CSS property.

In the case of SVG transform attributes, the rotation function is a bit different ? rotate(angle[ x y]) . The angle value works in the same way as for the similar CSS transform function (positive value means clockwise rotation, negative value means counter-clockwise rotation), but it has to be a unitless degree value.
