Violin plot
Definition
Depicts distributions of numeric data for one or more groups using density curves. The width of each curve corresponds with the approximate frequency of data points in each region. Densities are frequently accompanied by an overlaid chart type, such as box plot, to provide additional information.

Describe the variables, the shape of each distribution, and any notable features such as the width at different values, the presence of multiple modes, or differences between groups.

"Violin plots compare absolute relative error percentages for ANN, SVM, and RBFNN models. All distributions concentrate below 0.2 percent. SVM has the narrowest central spread, while ANN is broader at low values. RBFNN has the longest upper tail, extending above 1.2 percent, with additional density near 0.9 percent."
