To speed up the plotting process for the large datasets, ChemPlot comes with a PCA pre-reduction option that reduces the number of dimensions to 10 before applying the t-SNE or UMAP dimensionality reduction methods. Users can set the parameter to "True" to include the PCA pre-reduction step. In ChemPlot, the default plotting type is Scatter. In addition, ChemPlot provides Kernel Density Estimation (KDE) and Hexagonal plotting options. Figure shows the visualization of the same dataset by the three plotting types. Users can set the plotting type as shown below.
