      Draw lollipop chart.
  
      Parameters
      ----------
      mapping : `FeatureSpec`
          Set of aesthetic mappings created by `aes()` function.
          Aesthetic mappings describe the way that variables in the data are
          mapped to plot "aesthetics".
      data : dict or Pandas or Polars `DataFrame`
          The data to be displayed in this layer. If None, the default, the data
          is inherited from the plot data as specified in the call to ggplot.
      stat : str, default='identity'
          The statistical transformation to use on the data for this layer, as a string.
          Supported transformations: 'identity' (leaves the data unchanged),
          'count' (counts number of points with same x-axis coordinate),
          'bin' (counts number of points with x-axis coordinate in the same bin),
          'smooth' (performs smoothing - linear default),
          'density' (computes and draws kernel density estimate).
      position : str or `FeatureSpec`, default='identity'
          Position adjustment, either as a string ('identity', 'stack', 'dodge', ...),
          or the result of a call to a position adjustment function.
      show_legend : bool, default=True
          False - do not show legend for this layer.
      sampling : `FeatureSpec`
          Result of the call to the `sampling_xxx()` function.
          To prevent any sampling for this layer pass value "none" (string "none").
      tooltips : `layer_tooltips`
          Result of the call to the `layer_tooltips()` function.
          Specify appearance, style and content.
      orientation : {'x', 'y'}, default='x'
          Specify the axis that the baseline should run along.
          Possible values: 'x', 'y'.
      dir : {'v', 'h', 's'}, default='v'
          Direction of the lollipop stick.
          'v' for vertical, 'h' for horizontal, 's' for orthogonal to the baseline.
      fatten : float, default=2.5
          A multiplicative factor applied to size of the point.
      slope : float
          The baseline slope.
      intercept : float
          The value of y at the point where the baseline crosses the y axis.
      color_by : {'fill', 'color', 'paint_a', 'paint_b', 'paint_c'}, default='color'
          Define the color aesthetic for the geometry.
      fill_by : {'fill', 'color', 'paint_a', 'paint_b', 'paint_c'}, default='fill'
          Define the fill aesthetic for the geometry.
      other_args
          Other arguments passed on to the layer.
          These are often aesthetics settings used to set an aesthetic to a fixed value,
          like color='red', fill='blue', size=3 or shape=21.
          They may also be parameters to the paired geom/stat.
  
      Returns
      -------
      `LayerSpec`
          Geom object specification.
  
      Notes
      -----
      `geom_lollipop()` understands the following aesthetics mappings:
  
      - x : x-axis value.
      - y : y-axis value.
      - alpha : transparency level of the point. Accept values between 0 and 1.
      - color (colour) : color of the geometry. String in the following formats: RGB/RGBA (e.g. "rgb(0, 0, 255)"); HEX (e.g. "#0000FF"); color name (e.g. "red"); role name ("pen", "paper" or "brush").
      - fill : fill color. Is applied only to the points of shapes having inner area. String in the following formats: RGB/RGBA (e.g. "rgb(0, 0, 255)"); HEX (e.g. "#0000FF"); color name (e.g. "red"); role name ("pen", "paper" or "brush").
      - shape : shape of the point, an integer from 0 to 25.
      - size : size of the point.
      - stroke : width of the shape border. Applied only to the shapes having border.
      - linewidth : stick width.
      - linetype : type of the stick line. Codes and names: 0 = 'blank', 1 = 'solid', 2 = 'dashed', 3 = 'dotted', 4 = 'dotdash', 5 = 'longdash', 6 = 'twodash'.
  
      |
  
      When `slope=0`, the baseline cannot be parallel to the lollipop sticks.
      So, in this case, if `dir='h'`, the baseline will becomes vertical, as for infinity slope.
