    <div class="sphx-glr-thumbcontainer" tooltip="This is a simple example of using UMAP on the Fashion-MNIST dataset. The goal of this example is largely to demonstrate the use of datashader as an effective tool for visualising UMAP results. In particular datashader allows visualisation of very large datasets where overplotting can be a serious problem. It supports coloring by categorical variables (as shown in this example), or by continuous variables, or by density (as is common in datashader examples).">
