How can I create advanced visualizations in Kibana?

To create advanced visualizations in Kibana, you can use features like Lens, Vega, and Canvas. What specific visualization are you interested in?

I'm interested in using Vega for custom visualizations.

Great choice! Vega allows for complex visualizations. You can start by defining your data source and then use the Vega editor to write your JSON specification.

Can you give me an example of a simple Vega visualization?

Sure! A simple bar chart can be created by specifying the data source and defining the axes in the Vega JSON format. Would you like to see a sample code?

Yes, please share the sample code for a bar chart.

Here's a basic example:

{
  "$schema": "https://vega.github.io/schema/vega/v5.json",
  "data": [{
    "name": "table",
    "values": [
      {"category": "A", "amount": 28},
      {"category": "B", "amount": 55},
      {"category": "C", "amount": 43}
    ]
  }],
  "marks": [{
    "type": "rect",
    "from": {"data": "table"},
    "encode": {
      "enter": {
        "x": {"scale": "x", "field": "category"},
        "y": {"scale": "y", "field": "amount"},
        "width": {"scale": "x", "band": 1},
        "height": {"scale": "y", "field": "amount"}
      }
    }
  }]
}

This will create a simple bar chart.
