Those aren't updated clientside (have to ask the server for the new chart instead of just the data), which is a different architecture that does not scale.
Indeed, what I like about plotly is that you can start pretty much anywhere (R, Python, Jupyter, browser JavaScript, node.js, Julia, Matlab...) and get to an interactive, explorable chart (disclaimer, I'm working on WebGL plotly functions eg. https://twitter.com/plotlygraphs/status/747879741399568384)
Broken actually does a lot of stuff client side and you can simply update the data. It's much closer to d3 for interactivity,and really quite powerful. It does lack some features ATM, but it continues to grow space.
Shiny supports either model, depending on the visualization. And also I think you have it backwards, if you have to scale to large amounts of data then you want to push a chart, not data, into the client.
