<div> and <svg> attributes

<div> and <svg> attributes 1:

The <div> id should be changed so that it is unique in the HMI project.
Width and height should be the same for UserControl and SVG viewBox. SVG viewBox sets dimensions of the canvas that svg elements are placed on.
Attribute preserveAspectRatio="none" allows the SVG to be scaled without keeping its default proportions. Deleting this attribute means that the proportions will be maintained while scaling.
