  "alt": "Dot plot with a row for each measure and a dot for tracts, for counties weighted by residents and for counties counted once, on an axis of correlation. Life expectancy and homeownership have negative correlations, and the weighted county dot for life expectancy is farther from zero than the tract dot while the weighted county dot for homeownership is near zero. Poverty has a positive correlation that is similar across tracts and weighted counties, and upward mobility has negative correlations that overlap.",
  "caption": "The tract dots and the weighted county dots part for life expectancy and homeownership and sit together for upward mobility and poverty, and counting each county once moves the dots for life expectancy, mobility and poverty toward zero. A dot is a correlation of the index percentile with a tract measure, or with the population-weighted mean of that measure over a county's tracts, with a 95% interval from a bootstrap over counties. The county index is built from the county's own estimates.",
