The data that describes the choropleth value-to-color mapping is set in `z`. The geographic locations corresponding to each value in `z` are set in `locations`.

NAME
Chart::Plotly::Trace::Choropleth
DISCLAIMER
This is an unofficial Plotly Perl module. Currently I'm not affiliated in any way with Plotly. But I think plotly.js is a great library and I want to use it with perl.
METHODS
TO_JSON
Serialize the trace to JSON. This method should be called only by JSON serializer.
type
Trace type.
ATTRIBUTES
autocolorscale
Determines whether or not the colorscale is picked using the sign of the input z values.
colorbar
colorscale
Sets the colorscale. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example, `[[0, 'rgb(0,0,255)', [1, 'rgb(255,0,0)']]`. To control the bounds of the colorscale in z space, use zmin and zmax
customdata
Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, *scatter* traces also appends customdata items in the markers DOM elements
customdatasrc
Sets the source reference on plot.ly for customdata .
geo
Sets a reference between this trace's geospatial coordinates and a geographic map. If *geo* (the default value), the geospatial coordinates refer to `layout.geo`. If *geo2*, the geospatial coordinates refer to `layout.geo2`, and so on.
hoverinfo
Determines which trace information appear on hover. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.
hoverinfosrc
Sets the source reference on plot.ly for hoverinfo .
hoverlabel
ids
Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.
idssrc
Sets the source reference on plot.ly for ids .
legendgroup
Sets the legend group for this trace. Traces part of the same legend group hide/show at the same time when toggling legend items.
locationmode
Determines the set of locations used to match entries in `locations` to regions on the map.
locations
Sets the coordinates via location IDs or names. See `locationmode` for more info.
locationssrc
Sets the source reference on plot.ly for locations .
marker
name
Sets the trace name. The trace name appear as the legend item and on hover.
opacity
Sets the opacity of the trace.
reversescale
Reverses the colorscale.
selected
selectedpoints
Array containing integer indices of selected points. Has an effect only for traces that support selections. Note that an empty array means an empty selection where the `unselected` are turned on for all points, whereas, any other non-array values means no selection all where the `selected` and `unselected` styles have no effect.
showlegend
Determines whether or not an item corresponding to this trace is shown in the legend.
showscale
Determines whether or not a colorbar is displayed for this trace.
stream
text
Sets the text elements associated with each location.
textsrc
Sets the source reference on plot.ly for text .
uid
unselected
visible
Determines whether or not this trace is visible. If *legendonly*, the trace is not drawn, but can appear as a legend item (provided that the legend itself is visible).
z
Sets the color values.
zauto
Determines the whether or not the color domain is computed with respect to the input data.
zmax
Sets the upper bound of color domain.
zmin
Sets the lower bound of color domain.
zsrc
Sets the source reference on plot.ly for z .
