VegaLite

This integration automatically renders the VegaLite struct as a chart:

Vl.new()
|> Vl.data_from_values(iteration: 1..100, score: 1..100)
|> Vl.mark(:line)
|> Vl.encode_field(:x, "iteration", type: :quantitative)
|> Vl.encode_field(:y, "score", type: :quantitative)

Kino.VegaLite

Kino.VegaLite allows you to wrap an empty graphic and then stream data to the chart:

chart =
  Vl.new(width: 400, height: 400)
  |> Vl.mark(:line)
  |> Vl.encode_field(:x, "x", type: :quantitative)
  |> Vl.encode_field(:y, "y", type: :quantitative)
  |> Kino.VegaLite.new()
  |> Kino.render()

for i <- 1..300 do
  point = %{x: i / 10, y: :math.sin(i / 10)}
  Kino.VegaLite.push(chart, point)
  Process.sleep(25)
end
