These interactive grid-based visualizations were created with Plot.ly.
This heat map illustrates connections between data in a matrix. Individual values are shown as colors – the Y-axis shows a list of titles of correspondence, the X-axis shows machine-extracted features, and the Z-axis shows dates. Hover the cursor over different points on the map to see specific connections.
This bar chart shows relationships between two categories of data – machine-extracted features on the Y-axis and correspondence folders on the X-axis. The bars are shown in proportion to the features that they contain. Move the cursor over the bars to see the intersection between the data.
This timeline shows which machine-extracted features are occur in different correspondence over time. Move the toggle right or left to see the frequency of features by different years.
