• Readonlyguide.figure.purpose: "It is used to compare related views of data at a glance, such as the same measure for different groups or years."

• Readonlyguide.figure.appearance: "Picture a page divided into boxes like a window with several panes. Each box holds its own chart with its own axes, and you can enter one panel at a time."

• Readonlyguide.area.definition: "An area chart is a line chart with the space between the line and the bottom axis filled in."

• Readonlyguide.area.purpose: "It is used to show how an amount rises and falls over time, and to make the total size of that amount easy to feel."

• Readonlyguide.area.appearance: "A line runs from left to right, going up and down with the values. Everything below the line, down to the baseline, is filled in, so it looks like a mountain range seen from the side."

• Readonlyguide.boxen.definition: "A letter-value plot is an extended box plot that shows more cut points of the data, especially in the tails."

• Readonlyguide.boxen.purpose: "It is used for large data sets, where an ordinary box plot hides too much detail about the extreme values."

• Readonlyguide.boxen.appearance: "Each group looks like a stack of boxes centred on the middle value. The widest box holds the middle half of the data, and each smaller box further out holds a thinner slice of the tails, like a stepped pyramid."

• Readonlyguide.candlestick.purpose: "It is used in finance to read the opening, highest, lowest and closing price of a stock or currency for each period."

• Readonlyguide.candlestick.appearance: "Time runs from left to right, with one candle per period. Each candle is a thick body between the opening and closing price, with thin lines called wicks reaching up to the high and down to the low. The body is usually one colour when the price went up and another when it went down."

• Readonlyguide.candlestick_delta.definition: "A candlestick reference delta compares each candle of a candlestick chart with a reference line, such as a moving average."

• Readonlyguide.candlestick_delta.purpose: "It is used to tell how far above or below its usual level the price was in each period."

• Readonlyguide.contour.appearance: "Closed, wavy rings are drawn one inside another, like the rings on a hiking map around a hill. Each ring marks one value. Where the rings are close together the value changes steeply, and where they are far apart it changes gently."

• Readonlyguide.diverging_bar.definition: "A diverging bar chart shows bars growing in two opposite directions from a central line."

• Readonlyguide.diverging_bar.purpose: "It is used to compare two opposing sides, such as agree versus disagree answers, or men versus women in a population pyramid."

• Readonlyguide.diverging_bar.appearance: "A line runs down the middle. For each category, one bar extends to the left and another to the right. The length of each bar is its value, and the side tells you which group it belongs to."

• Readonlyguide.forest.definition: "A forest plot shows the results of several studies on the same question, one row per study, plus an overall combined result."

• Readonlyguide.forest.purpose: "It is used in medical research and meta-analysis to see whether studies agree and what their combined effect is."

• Readonlyguide.forest.appearance: "Studies are listed from top to bottom. Each has a small square at its estimate and a horizontal line showing its uncertainty. A vertical line marks \"no effect\". At the bottom, a diamond shows the pooled result."

• Readonlyguide.gantt.definition: "A Gantt chart shows tasks as bars along a timeline."

• Readonlyguide.gantt.purpose: "It is used in project planning to see when each task starts and ends, how long it takes, and which tasks overlap."

• Readonlyguide.funnel.definition: "A funnel chart shows how many items remain at each stage of a process."

• Readonlyguide.funnel.purpose: "It is used to find where items drop out, such as how many website visitors go on to sign up and then to buy."

• Readonlyguide.hist.definition: "A histogram shows how a set of numbers is distributed by counting how many fall into each range."

• Readonlyguide.hist.purpose: "It is used to see the shape of data: where most values are, how spread out they are, and whether the data leans to one side."

• Readonlyguide.hist.appearance: "Upright bars stand side by side with no gaps between them. Each bar covers a range of values along the bottom axis, and its height is how many values fall in that range."

• Readonlyguide.line.definition: "A line chart connects a series of values with a line, usually in time order."

• Readonlyguide.line.purpose: "It is used to show trends, such as how temperature or a stock price changes over days or years."

• Readonlyguide.directed_graph.definition: "A directed graph shows items, called nodes, joined by arrows that each point one way, from one node to another."

• Readonlyguide.directed_graph.purpose: "It is used to show how things lead to or depend on one another, such as the steps of a process, the parts of a system that call each other, or the layers of a neural network, so a reader can follow the arrows and see where paths branch, join or loop back."

• Readonlyguide.directed_graph.appearance: "Nodes are boxes or other shapes joined by arrows, usually laid out so that most arrows run the same way, from top to bottom or from left to right. Related nodes are often drawn inside a larger box."

• Readonlyguide.sunflower.definition: "A sunflower plot is a scatter plot where repeated points at the same spot are drawn as one mark with petals."

• Readonlyguide.sunflower.purpose: "It is used when many observations share exactly the same values, so that the number at each spot is not hidden."

• Readonlyguide.sunflower.appearance: "It looks like a scatter plot, but some dots have short lines sticking out of them like the petals of a flower. The number of petals is the number of observations at that spot."
