The web mapping approach to interactivity has limitations:

• Although the map is interactive in terms of panning, zooming and clicking, the code is static, meaning the user interface is fixed
• All map content is generally static in a web map, meaning that web maps cannot scale to handle large datasets easily
• Additional layers of interactivity, such a graphs showing relationships between variables and dashboards are difficult to create using the web-mapping approach
