Dash is a Python framework that allows developers to build web applications quickly and efficiently. It's ideal for data scientists and analysts who want to create interactive, web-based data visualizations.
One of the key features of Dash is its simplicity, with a minimal learning curve that makes it accessible to users without extensive web development experience. This is due in part to its use of Python, a language many data scientists are already familiar with.
Dash apps are built using a combination of Python functions and HTML templates, allowing developers to create complex, interactive interfaces with ease. This flexibility is a major advantage of using Dash, as it enables developers to create a wide range of applications, from simple dashboards to complex data visualizations.
Dash also has a large and active community, with many pre-built components and tools available to help developers get started quickly. This community support is a major advantage of using Dash, as it means developers can draw on the collective knowledge and experience of other users to help solve problems and overcome challenges.

What Is Dash
Dash is a cryptocurrency that aims to be the most user-friendly and scalable payments-focused cryptocurrency in the world.
Built on top of Plotly.js, React, and Flask, Dash ties modern UI elements like dropdowns, sliders, and graphs directly to your analytical Python code. You can create your first Dash app in under 5 minutes, as per their documentation.
Dash is marketed to both individual users and institutions, including merchants, financial services, traders, and those who need to send international remittances.
Dash's governance system, or treasury, distributes 10% of the block rewards for the development of the project in a competitive and decentralized way. This has allowed the creation of many funded organizations, including Dash Core Group.
Dash relies on a network of masternodes, which are servers backed by collateral held in Dash that are designed to provide advanced services securely and governance over Dash's proposal system.
Types and Usage
In printed English text, there are various types of dashes used to convey different meanings. An em dash or a spaced en dash can be used to mark a break in a sentence, and a pair can be used to set off a parenthetical phrase.
For example, in the sentence "Glitter, felt, yarn, and buttons—his kitchen looked as if a clown had exploded", the em dash is used to mark a break in the sentence.
An en dash is used to indicate spans or differentiation, where it may replace "and", "to", or "through". This is seen in the example "The French and Indian War (1754–1763) was fought in western Pennsylvania and along the present US–Canada border."
There are three main uses of the en dash: to connect symmetric items, to contrast values or illustrate a relationship between two things, and to compound attributes.
To connect symmetric items, an en dash is used to indicate ranges or alternatives, as seen in the example "The French and Indian War (1754–1763) was fought in western Pennsylvania and along the present US–Canada border."
A table can help illustrate the different uses of the en dash:
An em dash or horizontal bar is used to set off the source of a direct quotation, as seen in the example "..."
Formatting and Encoding
In some character encoding environments, like ASCII, an en dash can be hard to find. Two consecutive hyphens are often used as a substitute.
The en dash has a specific Unicode code point: U+2013 (decimal 8211). It's also represented in HTML by the named character entity –.
In some situations, the en dash is used as a substitute for the minus sign, especially when the minus sign character isn't available. This is because the en dash is usually the same width as a plus sign.
Spacing
Spacing can make a big difference in how en dashes are typeset. In most cases, en dashes are typeset closed up to the adjacent words or numbers.
For example, in "the 1914–18 war", the en dash is typeset closed up to the words "1914" and "18". This is also true for "the Dover–Calais crossing".
However, there's an exception when en dashes are used in setting off parenthetical expressions. In this case, they take spaces around them, as you can see in the example: "– such as this one –".
It's worth noting that the choice of em versus en in this context is discussed in more detail elsewhere.
Here's a quick rundown of the spacing rules for en dashes:
This means that en dashes are typically used to indicate ranges, and in those cases, they're typeset closed up to the surrounding words. But when they're used to set off parenthetical expressions, they take spaces around them.
Encoding and Substitution
The en dash is encoded in Unicode as U+2013 (decimal 8211) and represented in HTML by the named character entity –.
In some environments, like the ASCII character set, an en dash might be unavailable, so two consecutive hyphens are used as a substitute.
The en dash is sometimes used as a substitute for the minus sign, especially when the minus sign character is not available.
The en dash is usually the same width as a plus sign and is often available when the minus sign is not, making it a useful substitute.
However, the en dash cannot be used for a minus sign in programming languages because the syntax usually requires a hyphen-minus.
Em Dash Approximation with Hyphens
In environments where an em dash is unavailable, such as the ASCII character set, it's often approximated with consecutive hyphens.
The two-hyphen em dash proxy is a common convention, being a widespread practice in the typewriting era. It's still described in the Chicago Manual of Style as a way to approximate an em dash in hard copy manuscript preparation.
The three-hyphen em dash proxy was also used by some publishers, where the sequence of one, two, or three hyphens could correspond to the hyphen, en dash, and em dash, respectively.
However, it's worth noting that this convention is not always used consistently, and different styles may have varying preferences.
In American comics, the double hyphen became traditional due to early comic book letterers not being aware of the typographic convention of replacing a typewritten double hyphen with an em dash.
En versus Em
The en dash is traditionally half the width of an em dash, but in modern fonts, this is not always the case.
In fact, the length of the en dash is not standardized, and it's often more than half the width of the em dash.
The widths of en and em dashes have been specified as being equal to the widths of specific letters, but these specifications are not consistently followed.
For example, the en dash has been said to be the same width as a plus sign, which is useful in some situations, but not in programming languages.
In programming languages, the syntax usually requires a hyphen-minus, which is too narrow to make a typographically acceptable minus sign.
Relationships and Connections
The en dash is particularly useful in showing parallel relationships, as in the case of the McCain–Feingold bill or Bose–Einstein statistics. This is because the en dash represents the parallel relationship between the two entities.
In some cases, a hyphen can be used instead of an en dash, but the choice ultimately comes down to style. For example, the American Heritage Dictionary of the English Language uses hyphens in coordinate terms, while other styles, like AP Style or Chicago Style, prefer the en dash.
Here are some examples of how the en dash is used to convey relationships and connections:
- Australia beat American Samoa 31–0
- Mother–daughter relationship
- The Supreme Court voted 5–4 to uphold the decision
- New York–London flight
Relationships and Connections
In relationships and connections, the en dash is a powerful tool to convey meaning and clarity. It's used to contrast values or illustrate a relationship between two things, like in the example of Australia beating American Samoa 31–0.
The en dash is often used to show a parallel relationship between two people or entities, such as in the Taft–Hartley Act or the McCain–Feingold bill. This is different from using a hyphen, which is used for simple attributive compounds.
Sometimes, the choice between an en dash and a hyphen is a matter of style, not correctness. For instance, the American Heritage Dictionary of the English Language uses hyphens in coordinate terms, while AP Style or Chicago Style use en dashes.
In some cases, using an en dash can be ambiguous, like in the example of "New York–London flight". To avoid confusion, it's better to rephrase the sentence for clarity, as in "The flight from New York to London was a pleasant experience".

Here are some examples of how the en dash is used in relationships and connections:
- Australia beat American Samoa 31–0.
- Mother–daughter relationship
- The Supreme Court voted 5–4 to uphold the decision.
It's worth noting that the choice between an en dash and a hyphen can be a matter of personal preference, but it's always best to consult a style guide or dictionary to ensure consistency and accuracy.
Coin Circulation
Dash, a cryptocurrency, has a unique approach to coin circulation. Approximately 18.9 million Dash tokens can be issued in total.
The governance of Dash decides how to allocate 10% of block rewards to fund future proposals, which can impact the number of coins in circulation. If none are allocated, only 17.7 million Dash will be emitted.
New Dash tokens are created through a proof-of-work mining algorithm, with a token emission rate that decreases by one-fourteenth, or approximately 7%, every 383 days. This process is designed to slow down the creation of new coins over time.
Approximately 45% of new Dash is awarded to miners, 45% to masternodes, and 10% to fund future proposals.
