Carlos Orrego (Chile) is a software engineer and entrepreneur who has been working on visualization and data processing for more than 20 years. His work consists of the creation of large-scale artworks using a technique called "algorithmic art." Carlos and Andres incorporate real data to produce works of "data art." Art is a mechanism to interpret and understand reality. These artists feel it is their duty to explore the most diverse areas of our existence and make visible the invisible.
In this spiral histogram, each circle is a month-year temperature deviation from the corresponding 1951-1980 mean. Blue indicates a negative deviation from the mean (the darker the tone, the higher the deviation in absolute terms) while orange-red is a positive deviation from the mean (the stronger the tone, the higher the deviation in absolute terms).

This data represents the monthly mean CO2 mole fraction determined from daily averages (ppm) from March 1958 to January 2019. The darker the circle, the higher the concentration level.

This radial benchmark of the total Central Government Gross Debt and GDP for 25 LAC countries is shown yearly from 2006 to 2016 (millions of USD). The red rays show GDP, while blue rays represent Gross Debt for each country-year. All debt figures correspond to debt issued by the Central Government and the Central Bank and are end-of-period values. When applicable, they are expressed in millions of current US dollars using end-of-period exchange rates.

This image depicts the percentage resulting from the quotient of the total employed population divided by the working-age population. The employed are understood as those people who have worked at least one hour in the period of reference, or who are employed but have not worked due to extraordinary circumstances. The working-age population is defined by the lower age limit established in the survey used to collect employment data. The color red represents the male population, while blue represents women, and each line is a country-year.

This radial benchmark shows the prevalence of obesity by gender for 2-9 year old children in percentage of age group by country-year from 2000-2013. Girls are represented by yellow rays, while the brown color represents boys.

Total Factor Productivity (TFP) is defined as total output divided by human and physical capital in an economy. It is a residual measuring the efficiency in which accumulated factors of production can be used to produce outputs and is very relevant in explaining differences in income per capita across time and countries as well as growth rates.

Producer Single Commodity Transfers (%) by commodity, for 24 LAC countries, plus Canada and the USA, for 49 commodities for years 1986-2017. The annual monetary value of gross transfers from consumers and taxpayers to agricultural producers, measured at the farm gate level, arising from policies linked to the production of a single commodity such that the producer must produce the designated commodity in order to receive the transfer. The percentage values used are the SCT as a share of gross farm receipts for the specific commodity.

This radial benchmark shows investment in economic infrastructure for all subsectors by the private and the public sectors. Public and private investment in economic infrastructure is shown as a percentage of GDP for 20 LAC countries 2008-2016. Each ray is a year country, with purple for public investment and turquoise for private investment.

In this spiral histogram, each point is a ratio of total deposits from the public over total assets for a financial institution/year. It shows deposits from the public over total assets for close to 500 financial institutions from 19 LAC countries for seven years (2005, 2008, 2010, 2012-2015). The brighter the color, the higher the ratio.
