Using DevExtreme, HTML5 and Javascript to connect reusable data visualizations with updated data

Since 2012 keeps an open data catalog, with updated datasets. Besides, we report stories with open data published in Google Spreadsheets .

Most of these datasets are manually updated and we use Tableau Public to illustrate most of our stories with interactives as we cannot afford to have developers, we have only one.

Since 2013 our dataviz designer learned D3.js and javascript to develop our own visualizations and we detected many reusable ones that could serve as useful context information for many stories.

He selected DeveXtreme: a crossplatform HTML5 / Javascript tool to create responsive web applications for touch enabled devices and traditional desktops.

Examples 1)  Dollar: official and “blue” prices of dollar conversion to pesos, daily updated


Example 2) Central Bank stock of dollar reserves (Reservas del Banco Central) , weekly updated  Seguir leyendo

DATA as context integrated in content TAGS

As a way to enrich stories, adapted it´s CMS to integrate data as context in our content topical tags. Every news application or data platform we develop must be structured with this in mind so data as context can be distributed in topical or persons tags.

To do this, we first normalize names and then cross them with our TAGS database, and those that are in both datasets are automatically augmented by data or direct urls to our news applications.

For example: in a Legislator´s tag: her Statement of Asset, her path in politics, and even her profile can be presented, together with all the reporting.

Example 1) Person´s TAG: this is Elisa Carrio´s TAG – home page in
