Loading the captured records

Business words in the Trump account feed, by month

Each grain is one captured record, laid down in date order from the bottom. A month's layer is as thick as its record count. All six columns hold the same grains. A grain is lit where its record uses that group's words, so groups overlap. The wavy break is March 2022, which has no records. This is word use, not economic activity.
