The chart uses a log scale: equal steps up mean equal percentage gains.

Over 77 years the money doubled about 12.2 times. Without reinvesting dividends it would be $4,543,489: dividends account for 90% of the final value.
Inflation matters over this long. $10,000 in 1950 had the buying power of about $142,545 today, so the real gain is $46,828,171 against $142,545: still 328.5× the buying power, or 7.9% a year above inflation.
