Two hovering line charts are displayed in an SVG. The first line is red, and the second is green. When the mouse hovers over the first line, its stroke color changes to light gray. When hovering over the second line, its color shifts, and the cursor changes to a grab icon. The code uses CSS `:hover` pseudo-classes to alter the `stroke` property and cursor style of the SVG `path` elements. The paths are defined using SVG path data, with no data source specified.
