🔆 Introduction to Volcano Plot🔆 A volcano plot is a powerful type of scatter plot widely used in genomics, proteomics, and metabolomics to visualize the results of differential expression analysis — for example, comparing gene expression between two treatments or conditions. It combines statistical significance and magnitude of change in one easy-to-read graph. The x-axis represents the log₂ fold change (effect size) — how much a gene or protein is up- or down-regulated. The y-axis represents
