Rules that describe the data in Web Component

The outliers, found in the data, beside a threshold you typed

when: { op: 'outlier' }

This grid highlights the outliers found in the data itself, shown beside a fixed threshold you typed, so you can compare the two. It lets a rule describe the shape of the data rather than a hard-coded cutoff, so unusual values surface even when you did not know the number in advance.

Building…

Loading a live grid…

This is the web component version. A lattice-grid custom element renders the grid with no build step, its configuration set as a property, so it works on a page that has no bundler at all.

The configuration
