[Lens] Reduce chart switcher list items

[markov00]

The current chart switcher is very long and contains not just chart types, but chart type with style configurations like:

• pie and donut, where the main difference is just in the inner radius
• horizontal/vertical bar charts
• stacked/nonstacked/percentage

As described by @MichaelMarcialis here this list can be we could offer greatly simplified as:

• Line

• Area (consolidation of area, area percentage, area stacked)

• Bar (consolidation of bar horizontal, bar horizontal percentage, bar horizontal stacked, bar vertical, bar vertical percentage, vertical stacked)

• Bullet (consolidation of bullet horizontal, bullet vertical)

• Gauge (consolidation of gauge minor arc, gauge major arc, gauge circle)

• Heat map

• Metric

• Mosaic

• Pie (consolidation of pie and donut)

• Region map

• Table

• Tag cloud

• Tree map

• Waffle

And then we would allow the user to select things like orientation, stacked, percentage, donut hole, etc. elsewhere in the interface.

For bullet, gauge and pie I don't see any issue moving these configuration somewhere in the Visual options or somewhere in the Layer settings.

My main concerns with cartesian chart are the following:

• configuring stack/percent per chart is IMHO better then doing that per layer, because it avoid the dual axis configuration.
• configuring stack/percent per layer means that we are in favor of dual axis and it also requires the ability to switch quickly all layers in a single shot to simplify the curation of the chart.
• horizontal/vertical orientation should be applied to the entire chart, is not possible to mix orientations per layer
