Javier Abadía delivered the talk "Visualización de Datos Interactiva en aplicaciones con Vue.js y React" during the conference Codemotion Madrid 2019. We interviewed Javier asking him these questions: Which technologies would you recommend to implement interactive data visualization in a responsive and mobile-friendly web application? Based on your experience, what are the most common mistakes made by software developers when implementing data visualization applications? Do you have some suggestions in terms of frameworks and/or libraries that seem particularly promising for mobile developers? Comparing the different solutions that you tested for data visualization, do you think there are significant differences among them in terms of performance? When elections or moments like this happen, do you recommend any specific data visualization team from any newspaper or team that you are very fan of?
