"A volcano plot shows log 2-fold change on the x axis and negative log 10 p value on the y axis. Points form a dense central cluster near zero-fold change with wider spread toward both sides. Blue points on the left and orange points on the right indicate highly significant decreases and increases. Dashed threshold lines separate significant and non significant regions."
