Yes, but depending on the interactions it can get complex quickly. D3.js handles all the interactions in JS on the client. ContEx (elixir server-side charting) handles certain events (e.g. data point click) server side (see https://contex-charts.org/barcharts https://contex-charts.org/barcharts - turn on “show clicked bar” option). Showing data point detail, e.g. “On hover” would require client side code. (Disc: ContEx author)
