<div> and <svg> attributes

• 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.
