Data-capture

We help you to get and organize information from public data or different websites with scrapping.

Data-cleaning

We structure databases with information from multiple databases in multiple formats. Organization of information and standardization of variables.

Visualization apps

We create public data visualization applications so that your users can know and explore databases. We use the latest technologies in data visualization to communicate information.

Algorithms

We implement artificial intelligence algorithms to facilitate your work with data, from predictive algorithms to pattern recognition.

Web specials

We develop interactive web specials based on data. The specials have different visual components to guide your readers. See examples of our specials.

About us

Datasketch is a digital platform of investigative and data journalism. Our portal allows journalists, data scientists, social scientists and citizens in general to learn and consult on data visualizations, tools, software and in-depth research on various short-term issues. We have free data tools and different projects to bridge the gap between data and citizenship that facilitates the democratization of knowledge and a critical review of social realities based on information contrasts.

Santiago Ortiz, combining mathematical and artistic patterns

April 15, 2016

In the world of visualization there are many different faces: developers, inventors, mathematicians, designers. Santiago Ortiz is probably one of those characters that represents all and none of those at the same time.

 

In the world of visualization there are many different faces: developers, inventors, mathematicians, designers. Santiago Ortiz is probably one of those characters that represents all and none of those at the same time.

 

As a mathematician, Santiago combines creativity with hard work and a pragmatic approach to transform the reality behind bits and pixels into narratives based on data.

 

In 2010, Santiago, as co-founder of Bestiario (a Barcelona based company that creates products and services to transform the way we interact with data) designed a system to enhance the data analysis and visualization workflow. With his learnings of those years combining mathematical and artistic patterns, in 2012 he embraced into a self discovery project of exploration and experimentation. If you are interested you can check the details in his presentation at Eyeo 2014  (watch video).

 

During those 6 months of experimentation he asked himself these questions:

 

  • What I deeply love to do

  • What I'm exceptionally good at

  • What makes social sense



Armed with these motivation and from different learning exercises he reimplemented his old framework (originally in ActionScript) in Javascript. Among those initial projects it is worth noting these 3: Iliad, Seven set Venn diagramm and Lostalgic

 

Iliad

 

In his epic poem, Homer tells different stories that Santiago manages to visualize in terms of networks and co-occurrences of characters along time. The stream graph he developed helps understanding the different relations of characters along the poem.

 



Seven set Venn diagram

 

Venn diagrams show common elements of the sets being represented by intersections of the circles. We are more familiar with Venn diagramas when we have a small number of sets (2 or 3). Branko Grünbaum, after mentioning in 1975 that there didn't seem to exist a symmetrical representation for a 7 set Venn diagram, came up in 1992 with a non-monotonic and nice representation that Santiago finally used to make his interactive version.

The final version is done after depicting intersection areas with colors (instead of numbers), making sure that colors would be equidistant in hue.



 

Lostalgic

 

The once famous TV show Lost is being revived by Santiago with this interactive piece. It allows users to explore character's dialogues in 115 episodes along 7 seasons. The data was harvested from Lostpedia. This is a very innovative work that shows a very different way to interact with content displayed originally on TV. There are different controls to see relations among characters and reconstruction of each episode can be explored as a constellation with a linear flow for each scene.

 



And now…

After his exploration journey Santiago has participated in bigger projects with Twitter and The Economist. His portfolio, available at his home page (http://moebio.com) is a great inspiration for new projects. Now he is part of Red Drummer, a Brazilian company of dynamic data visualization from which he continues fascinated by different patterns that represent the complexity in our world. This complexity is pushing his boundaries and empowering him to abstract more and more the workflow for representing reality as information.
