Five examples of figures for a corralation table. In the top left, we see a heat map overlaid with a dendrogram. The heat map employs shades of red to indicate varying degrees of positive correlation among several variables, with lighter shades indicating stronger relationships. The dendrogram, a tree-like diagram, depicts the clustering of variables based on the strength of their correlations. The top right quadrant features scatter plots matrix (sometimes called a pairs plot) for various variable combinations. Each scatter plot shows the relationship between two different variables, with a Pearson correlation coefficient displayed prominently. Additionally, histograms along the diagonal show the distribution of each individual variable.The bottom left image presents a circular layout where variables are arranged around a circle, with curved lines connecting them. The thickness and color of the lines indicate the strength and nature of the correlation (positive or negative), and alongside each line, the corresponding correlation coefficient is displayed. The center image features a somple heat map . The heat map employs shades of red to indicate the varying degrees of positive correlation and purple shades for negative correlations. The more solid the color is, the closer to one or negative one. Finally, the bottom right section contains a classic correlation matrix, with squares colored on a gradient from blue (negative correlation) to red (positive correlation). A scale on the right side indicates the range of correlation values, and the matrix is symmetrical about the diagonal, which is left blank, emphasizing the redundancy of mirroring values.

Two examples of tables rendered side-by-side. The top example titles Bottom Alignment which is an example of how you can set up 2 tables next to each other aligned by the bottom lines of the tables. The bottom example titles Top Alignment and this one has two tables set side-by-side but aligned by the lines on the top. Both examples also shows captions for each table and the overall figure formed by the tables set side-by-side.
