1Point21 Interactive, a U.S.-based data visualization and content marketing agency, has created a series of visualizations depicting the dangers of celebratory gunfire. The visualizations show how gravitational forces, firing angle, speed, atmospheric data, and the type of gun or bullet affect a bullet’s trajectory and resultant damage. One visualization displays estimated trajectories for five popular types of bullets shot at different angles next to the Burj Khalifa, the tallest building in the world, and Mount Fuji. The visualization displays trajectories in red if the bullet is traveling fast enough to penetrate a human skull and blue if not. According to the visualization, most bullets reach a high enough velocity to penetrate a skull by the time they return to the ground.
