The Joint Research Centre has cultivated significant expertise in developing Voilà dashboards using Python for scientific data visualization, resulting in the design and deployment of many real-world web applications. This presentation will highlight our commitment to building a robust Voilà developer community through dedicated training and resource libraries. We will introduce and demonstrate our innovative meta-dashboards, which streamline the creation of complex, multi-page dashboards by automating framework and code generation. A live demonstration will illustrate the ease of building a geospatial application using this tool. We will conclude with a showcase of recently developed Voilà dashboards in areas such as agricultural/biodiversity surveys and air quality monitoring, demonstrating their effectiveness in data exploration and validation.
