To answer the question regarding the approximate time when the first data visualization occurred, we can assess the historical context of data visualization.

1. Early 1800s: This period saw the emergence of statistical graphics, with the work of figures such as William Playfair, who created various types of charts including bar and line graphs.

2. Jurassic Era: This time frame is geological (about 145 to 200 million years ago) and is not applicable to the development of data visualization, which is a human activity.

3. Pleistocene Era: This era (approximately 2.6 million to 11,700 years ago) primarily pertains to the evolutionary history of humans and predates the formal concepts of data and statistics.

Based on this analysis, the most accurate answer regarding when the first data visualization took place would be Early 1800s.

Final Answer

Early 1800s.
