Project: svg-solar
Task (easy): Import `assets/data.json` as an object `data` whose `bodies` attribute contains all the planets data. Mark each bodies item as body. Add planet elliptical orbits (svg path, id `orbit_{body.name}`, class `orbit`, no fill, line color is white, line width is 0.1) to systemRoot. Each orbit's center is system center, rx is `body.rx`, ry is `body.ry`. Each orbit path's start point is the right point of the ellipse.
