HTML Visualizations are very powerful within SM when it comes to collect data from various tables and present them to the user in a user friendly, state-of-the-art way.
But the HTML viewer is currently limited to pure HTML and CSS which obviously limits the possiblities.
We would suddenly be able to visualize data dependencies in a modern and interactive way.
Many records within SM have relationships and follow hiearchies e.g. departmenty, locations, cost centers - but also Incidents, Changes etc. have n:n relationships (screlation table).
A framework like D3 would allow to visualize such data much more efficiently - imagine this could be done directly within the SM UI. Currently we have to build separeate webapplications and integrate them through REST. This leads to separate UIs and does not provide the best user experience.
