These features make Plotly very suitable for data analysis and presentation, especially when the data is presented visually, helping you to better understand it.
Benefits of JavaScript Plotly
Easily create beautiful graphs
One of the biggest advantages of Plotly is that it allows you to easily create beautiful graphs. Even if you are a programming novice, you can intuitively create professional-looking graphs. This advantage is especially helpful when making presentations or reports.
- Plenty of templatesThere are various design templates available, so you can choose the one that suits your taste.
- Easy to customize: You can easily change the color, font, and size to create your own original graph.
- Drag and drop functionality: You can easily adjust the layout of your graph by dragging elements.
For example, if you are using it for a school project, you can input your data and have a beautiful graph created in just a few minutes, saving you time and making effective presentations.
Can handle large amounts of data
Plotly is also excellent at handling large amounts of data. It can display thousands or tens of thousands of rows of data at once, making it suitable for analyzing big data. This advantage is particularly useful for data analysis in research and business.
- Logarithmic Scale: Large numerical data can be easily displayed by using a logarithmic scale.
- Filter function: You can display only the data you need or narrow it down by specific conditions.
- Easy data import: You can easily import data from Excel or CSV files and instantly display it in a graph.
For example, if you have collected hundreds of scientific experiment data, you can use Plotly to easily graph the results and visually analyze them, helping you understand the data more deeply.
Lots of interactive features
Plotly is unique in that it offers rich interactive features that allow you to explore your data in greater depth, allowing you to interact with the visual representation of your data and deepen your understanding.
- Hover Features: You can view detailed data by placing your mouse over the graph.
- Zoom function: You can zoom in on specific areas to get a closer look, allowing you to check even the most minute details.
- Filtering Function: You can display only specific data, making it easy to extract the information you need.
For example, by selecting a specific period in a graph showing stock price fluctuations and conducting detailed analysis, you can make investment decisions. In this way, interactive features make data analysis more efficient and aid in visual understanding.
Disadvantages of JavaScript Plotly
A bit of a steep learning curve
One of the disadvantages of Plotly is that it has a somewhat steep learning curve. Especially for those who are not familiar with programming, you may be confused about the initial settings and usage. This may make it difficult to get the hang of it right away.
- Difficulty in initial setup: Setting up the environment and installing libraries can be time-consuming.
- Understanding the documentation: You will need to read the provided manual, which can be quite jargon-heavy.
- Lack of support for beginners: It can be difficult to learn on your own as there are few tutorials for beginners.
For this reason, you may be confused at first, but as you get used to it little by little, you will be able to use it well. In particular, by referring to the official samples, it will be easier to understand how to actually use it.
Large projects are expensive
Plotly is basically free to use, but it may be costly to use for large projects. In particular, for commercial use, a license may be required. Please be aware of this.
- Commercial License: For corporate use, license fees may apply.
- Restrictions: Some functions are limited in the free version, so you will need to choose a paid plan to use the features you need.
- Support differences: The free plan offers limited support, so it can be difficult to resolve issues when they arise.
For example, even if you can use it for free for a school project, you need to consider the cost if you want to use it for data analysis in a company. For this reason, it is important to choose the appropriate plan according to your budget.
Can be heavy compared to other libraries
Because Plotly has many features, it can run slower than other libraries. In particular, if you have a large amount of data, it may take a long time to display, so please be careful.
- Slow load times: When loading a large amount of data, it may take some time to display.
- Browser Load: It may run slowly, especially on older computers and smartphones.
- Performance Limitations: Using advanced interactive features may slow down the operation.
For example, when dealing with tens of thousands of rows of data, using Plotly may take longer to display than other tools. In particular, when using many interactive functions, performance may be reduced because it depends on the processing power of the browser. In such cases, the user experience may be impaired, so it is also important to consider other lightweight libraries depending on the scale of the project and the amount of data.
JavaScript Plotly vs. other libraries
Plotly vs Google Charts
Plotly and Google Charts are both data visualization tools, but they have different features.
- Operability: Plotly is good at interactive graphs and is easy to handle complex data, but Google Charts has a simple interface and is easy to use.
- Design freedom: Plotly offers a wide range of customization options, allowing you to change the appearance as you like, whereas Google Charts has many default styles and customization can be time-consuming.
- Handling of Data: Plotly can handle large amounts of data and is particularly suitable for use in scientific and technical fields, while Google Charts is lightweight and better for displaying simple data.
For example, the simplicity of Google Charts may be suitable for an educational project, but if you're analyzing research data, Plotly may be a better choice.
