① This example demonstrates how to dynamically construct a histogram in GeoGebra to visualize data distribution, allowing users to adjust parameters and observe changes in the graph. ② Core mathematical concepts include data grouping, frequency counting, histograms and frequency distributions, with extensions to linear programming, logarithms, parabolas, fractal geometry, and subtraction. ③ Construction highlights: based on the summary, it uses GeoGebra commands such as Point, OrthogonalLine, Polygon, and RotateText, involving objects A through U, V, W, Z, and subscripted points. Rectangular bars are drawn using polygons, perpendicular lines assist positioning, and rotated text labels annotations. ④ Suitable for middle school statistics and probability lessons, as well as introductory college data analysis, helping learners understand data visualization and distribution characteristics.
