T-SNE representation based on the distance in the space of systems (upper panel) and distance in the space of disc parameters (lower panel). The upper panel is similar to Fig. 8, upper panel, except that here the colour-coding is only linked to the position of the point on the plot. In the lower panel, we used T-SNE based on the similarity resulting from the metric in the space of disc parameters (see text) to represent systems. The colour-coding indicates in which part of the upper panel the same system is represented. In the lower panel, two points located close to each other represent planetary systems formed in similar discs, whereas two points with similar colours represent planetary systems that are themselves similar. An animation is available online.
