Generate a horizontal bar chart to show data for numerical comparisons among different categories, such as, comparing categorical data and for horizontal comparisons. Hosted by Darwin using AntV's public free renderer. Returns a PNG image. Accepts at most 50 rows with bounded image sizes. No API key is required; payments are not supported.
Whether grouping is enabled. When enabled, bar charts require a 'group' field in the data. When `group` is true, `stack` should be false.
Whether stacking is enabled. When enabled, bar charts require a 'group' field in the data. When `stack` is true, `group` should be false.
Set the theme for the chart, optional, default is 'default'.

}Generate a column chart, which are best for comparing categorical data, such as, when values are close, column charts are preferable because our eyes are better at judging height than other visual elements like area or angles.
