This bar graph sample shows the number of speakers for the most spoken languages of the world.
"In the philosophy of language, a natural language (or ordinary language) is any language which arises in an unpremeditated fashion as the result of the innate facility for language possessed by the human intellect. A natural language is typically used for communication, and may be spoken, signed, or written. Natural language is distinguished from constructed languages and formal languages such as computer-programming languages or the "languages" used in the study of formal logic, especially mathematical logic. ... Though the exact definition varies between scholars, natural language can broadly be defined in contrast on the one hand to artificial or constructed languages, computer programming languages like Python and international auxiliary languages like Esperanto, and on the other hand to other communication systems in nature, such as the waggle dance of bees. Although there are a variety of natural languages, any cognitively normal human infant is able to learn any natural language. By comparing the different natural languages, scholars hope to learn something about the nature of human intelligence and the innate biases and constraints that shape natural language, which are sometimes called universal grammar. The term "natural language" refers only a language that has developed naturally, and hence to actual speech, rather than prescribed speech. Hence, unstandardized speech (such as African American Vernacular English) is natural, whereas standardized speech such as Standard American English, which is in part prescribed, is somewhat artificial."

This divided bar chart sample shows the petroleum products yielded from 1 barrel of crude oil in California in 2004. It was drawn using data from the chart on the California Energy Almanac website. [energyalmanac.ca.gov/ gasoline/ whats_ in_ barrel_ oil.html]
"Petroleum products are useful materials derived from crude oil (petroleum) as it is processed in oil refineries. Unlike petrochemicals, which are a collection of well-defined usually pure chemical compounds, petroleum products are complex mixtures. The majority of petroleum is converted to petroleum products, which includes several classes of fuels.
According to the composition of the crude oil and depending on the demands of the market, refineries can produce different shares of petroleum products. The largest share of oil products is used as "energy carriers", i.e. various grades of fuel oil and gasoline. These fuels include or can be blended to give gasoline, jet fuel, diesel fuel, heating oil, and heavier fuel oils. Heavier (less volatile) fractions can also be used to produce asphalt, tar, paraffin wax, lubricating and other heavy oils. Refineries also produce other chemicals, some of which are used in chemical processes to produce plastics and other useful materials. Since petroleum often contains a few percent sulfur-containing molecules, elemental sulfur is also often produced as a petroleum product. Carbon, in the form of petroleum coke, and hydrogen may also be produced as petroleum products. The hydrogen produced is often used as an intermediate product for other oil refinery processes such as hydrocracking and hydrodesulfurization." [Petroleum product. Wikipedia]
