Tulpdiagrammide

Tulpdiagrammide is a term used in information visualization to refer to a family of diagrams sometimes described as tulip diagrams. The word combines the Dutch word tulp, meaning tulip, with diagramm or diagram, reflecting a design that resembles the silhouette of a tulip. The phrase is encountered in multilingual texts and does not have a single universally accepted definition.

A tulip diagram is designed to present multiple quantitative variables for one or more entities in a compact, visually distinct form. A typical design features a central stem from which several petals radiate. Each petal encodes a variable, with its length or width representing the value, and color or texture providing additional attributes such as category or group. The arrangement of petals is intended to evoke a tulip shape, aiding recognition and comparison at a glance.

Construction and variants vary across implementations. Some designs place petals evenly around a circle, while others align them along a vertical axis with a crown-like top. Normalization is commonly applied to allow comparison across variables with different scales. While several software tools offer tulip-diagram capabilities, there is no universal standard for their geometry, labeling, or color conventions.

Usage and interpretation are most effective for small to moderate numbers of variables (roughly four to a dozen) and when a compact visual summary for a single object or a small set of objects is desired. They are often used in exploratory data analysis and in illustrative figures for horticultural, ecological, or design-related datasets. Limitations include potential ambiguity in petal ordering, scaling effects, and color interpretation, which can challenge accurate reading without clear documentation.
