The width and transparency of the path represent the strength of the correlation (wider and less transparent = stronger correlation).įor example, it can be seen that the positive correlation between Ozone and Temp is stronger than the positive correlation between Ozone and Solar.R.Ĭoursera - Online Courses and Specialization Data science Blue color represents a positive correlation, and a red color corresponds to a negative correlation. The positioning of variables is handled by multidimensional scaling of the absolute values of the correlations.įor example, it can be seen from the above plot that the variables Ozone, Wind and Temp are clustering together (which makes sense).Įach path represents a correlation between the two variables that it joins. Variable that are highly correlated are clustered together. The option min_cor indicates the required minimum correlation value for a correlation to be plotted.Įach point reprents a variable. The R function network_plot() can be used to visualize and explore correlations.
