// - value_column: the column to show in the heatmap boxes
// - max_value: if present, all values greater than this value will be set to the maximum color
// - min_value: if present, all values less than this value will be set to the minimum color
// - color_gradient: if present, overrides the green/red gradient. Should be an array of strings, where each value is a hex color string
// - html_element: The element to add the heatmap to
// - title: The title of the heatmap
// - x_label: The title to show above the x_column values
// - y_label: The title to show above the left column of the heatmap with y_column values
// - value_is_percent: a bool (default false). If it's true, the values will be formatted using d3.format as a percent
