An interactive solar system visualization allows users to click on a planet to reveal its atmospheric composition and temperature data. A central SVG diagram animates planets orbiting the sun using SVG `<animateMotion>` with `<mpath>` elements. Selecting a planet toggles the visibility of its corresponding D3.js pie chart and line chart, built with `d3.pie` and `d3.line`, displaying atmospheric gas shares and temperature against distance. The data is static and embedded in the script files.
