Data analysis & visual storytelling

This collection of projects is done with tools like Tableau Public and R, plus some basics of HTML and CSS. Many of these publications are part of my courses and workshops in Latinamerica, where I train and teach journalist and citizens on how to analyze databases and craft a data visualization with journalistic precision and effective storytelling.

Visual & audio

There was a time in Central America when Hondurans were the second population that emigrated least from the region. Three decades ago, for every 10 thousand inhabitants, only 316 left their land. Now they do it, at least, 780. Why are they being pushed until they leave their country?

Data visualization

The silenced, is a data visualization about femicides in Costa Rica. It visually documents the murder of 337 women, assassinated by their partners, between 2007 and 2018. It was published to create awareness
about women violence.

Animated graphics with R

The generation of graphics is an essential part of the exploratory and explanatory analysis of the data. For that reason I also generate visualization of static and animated information using R -the statistical programming languaje-  and its libraries Ggplot 2 and Gganimate.

Visual data analysis

Visual investigation

Although at a country level it is expected that the aging will begin after 2040, this analysis, based on population forecasts, shows that senescence will reach between two and 14 years in half of the cantons of the country.

Visual investigation

This project shows how in Costa Rica, there are fewer and fewer mothers under the age of 19. The country has achieved the most significant historical decline thanks to a province in particular, Limón. In it, the number of young people who gave birth between the beginning of this century and last year decreased by almost half.

Infographic

In Guadalajara, every day there is a good influx of rentiers looking for a bike in the city. Per day, the number of journeys ranges between less than 7,000 ( first quartile ) and more than 11,500 ( third quartile ). Of course, this means of transport is never as indispensable as Tuesdays, Wednesdays and Thursdays. In those three days there were 1.7 million routes, half of all the events in 2018, according to an analysis of The Data Counts with data from the MiBici public service.

In the world of Latin letters, no one like Mexican writers and writers have garnered so many awards in the history of the Guadalajara International Book Fair (FIL). Since 1991, when the FIL Prize for Literature in Roman Languages was established and until this year, the work of seven Mexicans has been praised and recognized. The last of them is the poet, essayist and translator David Huerta, who received the award on November 30 in the capital of Jalisco.

The “Fewer Children in Classrooms” project is the first online application that enables making interactive comparisons in the enrollment in elementary 4.000 schools throughout the country.

Till death do us part?

For almost three decades, divorces have increased in Costa Rica. How many divorces are signed for every 100 weddings held? How much has that ratio changed between 1990 and 2016?
