Returns figure for a gantt chart
:param (array|list) df: input data for gantt chart. Must be either a
a dataframe or a list. If dataframe, the columns must include
'Task', 'Start' and 'Finish'. Other columns can be included and
used for indexing. If a list, its elements must be dictionaries
with the same required column headers: 'Task', 'Start' and
'Finish'.
:param (str|list|dict|tuple) colors: either a plotly scale name, an
rgb or hex color, a color tuple or a list of colors. An rgb color
is of the form 'rgb(x, y, z)' where x, y, z belong to the interval
[0, 255] and a color tuple is a tuple of the form (a, b, c) where
a, b and c belong to [0, 1]. If colors is a list, it must
contain the valid color types aforementioned as its members.
If a dictionary, all values of the indexing column must be keys in
colors.
:param (str|float) index_col: the column header (if df is a data
frame) that will function as the indexing column. If df is a list,
index_col must be one of the keys in all the items of df.
:param (bool) show_colorbar: determines if colorbar will be visible.
Only applies if values in the index column are numeric.
:param (bool) show_hover_fill: enables/disables the hovertext for the
filled area of the chart.
:param (bool) reverse_colors: reverses the order of selected colors
:param (str) title: the title of the chart
:param (float) bar_width: the width of the horizontal bars in the plot
:param (bool) showgrid_x: show/hide the x-axis grid
:param (bool) showgrid_y: show/hide the y-axis grid
:param (float) height: the height of the chart
:param (float) width: the width of the chart

:param (list|tuple) endpts: takes an increasing sequece of numbers
that defines intervals on the real line. They are used to group
the entries in an index of numbers into their corresponding
interval and therefore can be treated as categorical data
:param (str) diag: sets the chart type for the main diagonal plots.
The options are 'scatter', 'histogram' and 'box'.

colormap_type is forced to 'cat' or categorical
:param (str) colormap_type: determines how colormap is interpreted.
Valid choices are 'seq' (sequential) and 'cat' (categorical). If
'seq' is selected, only the first two colors in colormap will be
considered (when colormap is a list) and the index values will be
linearly interpolated between those two colors. This option is
forced if all index values are numeric.
If 'cat' is selected, a color from colormap will be assigned to
each category from index, including the intervals if endpts is
being used

The only forbidden parameters are 'size', 'color' and
'colorscale' in 'marker'
