confederacy.png
This image displays a line graph set against a white background with a light gray grid overlay. At the top center, there is a legend consisting of a small blue square followed by the text "confederacy".

The horizontal x-axis represents time in years. The labels are spaced at ten-year intervals, starting from 1850 on the far left and extending past 2000 on the right. The specific year markers visible along the bottom are: 1850, 1860, 1870, 1880, 1890, 1900, 1910, 1920, 1930, 1940, 1950, 1960, 1970, 1980, 1990, and 2000.

The vertical y-axis on the left represents a numerical value expressed as a percentage. The scale is very granular with labels ranging from 0.0000000% at the bottom to 0.0009000% at the top. The intervals between labels are increments of 0.0001000%.

A single blue line plots the data for "confederacy".
- At the start in 1850, the line is near its highest point on the graph, hovering just below the 0.0009000% mark.
- Between 1850 and roughly 1870, there is a steep decline. The line drops rapidly from the top left corner down towards the middle of the chart.
- From 1870 to about 1910, the line continues to descend but with more fluctuation (ups and downs) compared to the initial drop. It moves from around the 0.0005000% level down toward the 0.0002000% level.
- From roughly 1910 onwards, the line flattens out significantly as it approaches the bottom of the chart (near 0.0000000%).
- Between 1950 and 1970, there is a very slight rise, creating a small bump in the line.
- After 1970, the line drops again to near zero.
- From roughly 1980 through the end of the graph (past 2000), the blue line remains extremely close to the bottom axis, indicating a value very close to 0.0000000%.

The overall trend shows a dramatic decrease in the measured value from 1850 to roughly 1920, followed by a long period of stability at a near-zero level for the remainder of the timeline shown.
